3. Campus Projects to Reform Undergraduate and Graduate STEM Education


A New Integrated Approach to Undergraduate Course Instruction

Howard Hughes Medical Institute Award
Yi Lu
Chemistry

Dr. Lu proposes developing a new integrated, inquiry-based course involving all levels of undergraduate students, from freshmen to seniors, with the theme of the role of chemistry in life and society. The course will help recruit, motivate, and retain minority students as science majors. The course will be a single class that spans the four-year undergraduate education; students may take up to one semester per year. First-time students will attend lectures as well as presentations by other students. They will also choose an open-ended topic to research. The second time students take the course, they will give a literature seminar on their chosen topic. The third time, they will give a proposal seminar on how they will investigate their topic and resolve problems. The fourth time, they will give a seminar to report the results of their investigations.

Students at all levels who have similar topics will be put into groups to work together; seniors will be expected to act as mentors to the more junior students. In addition, each group will be assigned a more senior mentor, such as the instructor, a teaching fellow, a graduate teaching assistant, or a research assistant. The goal of the course is to interest students who may not otherwise choose science courses or a science major. In addition, to recruit minority students from other universities, the course will be offered in the summers and fellowships will be provided to defer expenses.


An Institutional NRSA in Molecular Biophysics

National Institutes of Health Award #2T32GM008276
Colin Wraight
Biochemistry, Molecular and Cellular Biology
Project Dates: 7/1/2009–6/30/2014

This engineering education research award to the University of Illinois at Urbana-Champaign will employ researchers to investigate the learning mechanisms and benefits to engineering education of popular and rapidly expanding international service learning projects. These projects are believed to elicit many of the competencies for future engineers described as essential by the National Academy of Engineering and engineering education accreditation boards. The results of this research will enable the development and dissemination of research-based educational materials for project-centered service-learning experiences for engineers. It will also lead to the discovery of models and pedagogical approaches for incorporating key features of co-curricular international project work into the mainstream of instruction and curriculum reform. International projects may be a powerful means to provide preparation for professional practice, developing knowledge and competencies in meaningful contexts that are applicable for both domestic and international engineering projects. The acquisition of these competencies will better prepare engineering students to participate in a more globally competitive workforce.


An Integrated Lab-on-a-Transistor for Biological Detection

National Science Foundation Award #1028549
Rashid Bashir
Electrical and Computer Engineering
Project Dates:10/01/2010–9/30/2014

The crisis in the management of infectious disease for the developed world and in the developing world (global health arena) requires rapid, easy to use, integrated, and inexpensive diagnostic devices for the detection of agents of infectious diseases, i.e., bacteria, viruses. In this application, the development of a “Lab-on-a-Transistor” is proposed for cell capture and thermal lysing, and ultra rapid techniques for performing nucleic acid amplification on silicon transistors with a direct, rapid electrical detection of the amplified products. The grand challenge of making nucleic acid amplification truly a point-of-care test will be addressed, where the results can be obtained with high accuracy and reliability in less than 5 minutes on a silicon sensor array. To address these challenges, the bacteria Listeria monocytogenes will be used as the model system within the three years of this proposed grant but the technology platform can be applied to other pathogenic microorganisms as well.

Lab-on-a-Transistor will (a) concentrate single bacteria on individual field effect transistors within a linear array using dielectrophoresis within a microfluidic channel. Then ultra-localized heating on the surface of the field effect sensor using an ac voltage will be explored. Using this method, thermal lysing of bacteria that are attached on the surface of the transistors will be performed by achieving temperatures of 95°C or higher. (b) The same sensor would be used as a heater to perform nucleic acid amplification reactions using either a polymerase chain reaction or a rolling circuit amplification method. (c) We will explore the use of the transistors themselves for label free electrical detection of the PCR products. The proposed work will have a broad impact in the area of silicon-based biosensors and the proposed technology could provide significant advances in developing point of care sensors.

Education Component: Graduate students will be involved in summer lecture and hands-on workshops to be held at the Micro and Nanotechnology Laboratory at the University of Illinois. REU summer support will be requested for hiring additional undergraduates to work with the graduate students on the research project during the summer, which will also help to develop a pipeline of graduate student researchers for the future.


CAREER: Advancement of Microalgal Biotechnology via Quantitative Sustainable Design: An Integrated Research and Education Plan

National Science Foundation Award #1351667
Jeremy Guest
Civil and Environmental Engineering
Project Dates: 05/15/2010 – 4/30/2019

This project will advance the frontier of microalgal biotechnology through the integration of experimentation, modeling, and quantitative sustainable design (QSD), and will leverage this framework to improve the education and retention of a diverse student body in environmental engineering. Research will pursue energy-positive nutrient recovery from wastewater with microalgae, and will focus on overcoming critical knowledge gaps that limit our ability to design mixed community microalgal bioprocesses that might bring this transformation within reach. Objectives of the research are (i) to elucidate the mechanisms governing microalgal bioprocess performance across a landscape of possible designs, and (ii) to establish a path forward for energy positive nutrient (nitrogen and phosphorus) recovery from wastewater. Experiments with mixed communities of microalgae treating wastewater will be coupled with modeling to advance understanding of how key design parameters influence process performance, microbial community structure and function. These findings will be integrated in a QSD framework (including life cycle assessment, life cycle costing, sensitivity and uncertainty analyses) to identify technology targets and chart a path forward for microalgal wastewater biotechnology development.

Research efforts will be integrated with an education plan designed (i) to increase the intrinsic motivation of minority and female students in introductory- and advanced-level environmental engineering courses through an aspirational resource management framework, and (ii) to increase awareness of and ability to navigate trade-offs among environmental, economic, and performance sustainability criteria for engineered systems. These goals will be achieved by developing two online course modules that will be designed, tested, and deployed at UIUC, Bucknell University, and Parkland College. Modules will be designed through cognitive labs and will include external, independent formative and summative evaluations.

The project is aimed at developing a fundamental understanding of thermal transport in soft and hard matter, and across interfaces separating these materials. This understanding may lead to new pathways for developing small-scale transistors, discovering new cancer therapies, and creating novel energy harvesting thermoelectric materials.

Current approaches to nutrient management at wastewater treatment plants (WWTPs) use costly, energy-intensive processes that rely on bacteria and chemicals to remove nitrogen and phosphorus. This research will re-envision nutrient management at WWTPs by utilizing native microalgae for energy-positive biological nutrient recovery. In addition to increasing the embodied chemical energy of wastewater more than 2-fold, this approach may also advance the limit of technology by overcoming the critical barrier of dissolved organic nitrogen, a form of N that is often unable to be removed by existing nutrient removal processes but which can be rapidly assimilated by microalgae. The core concept of the research plan is microalgal technology development can be expedited through integration of experimentation, modeling, and QSD. This integrated process will elucidate molecular-scale barriers to systems-scale sustainability and seek to overcome them through process design. This approach will enable the setting of targets for technology performance, and identify critical areas for future research to achieve long-term adoption and sustainability. The research activities will be coupled with educational activities to increase the attraction and retention of underrepresented students by focusing on aspirational outcomes of environmental engineering and developing a new platform for education in sustainable design.


CAREER: Anharmonic Dynamics of Thermal Transport in Nanotransistors and Across Hard-Soft Interfaces

National Science Foundation Award #0954696
Sanjiv Sinha
Mechanical Science and Engineering
Project Dates: 02/01/2010 – 1/31/2015

This project is aimed at tailoring phonon transport phenomena in nanostructures through the control of coherence and anharmonicity effects. Coherence-scale phenomena are prominent in, for example, field-effect transistors while anharmonicity affects transport at interfaces separating hard and soft matter. The long-term goal of this project is to enable and advance pertinent applications ranging from nanoelectronics to nanomedicine. Theoretical tools will be developed to analyze coherence effects, while novel experiments will be devised and conducted to probe the spectral properties of phonons participating in thermal transport at hard-soft interfaces.

A systematic investigation of the role of anharmonicity (in soft matter) and coherence (in hard matter) during thermal transport will be conducted. A phonon wave transport theory will be extended to include particle-like behavior to enable the prediction of thermal responses in sub-10 nanometer transistors. A novel time-resolved Raman scattering approach to experimentally probe temperature-dependent anharmonic shifts in the frequencies of macromolecules will also be developed, providing a means to gain insight into the anharmonic dynamics of phonons in soft matter.

The project is aimed at developing a fundamental understanding of thermal transport in soft and hard matter, and across interfaces separating these materials. This understanding may lead to new pathways for developing small-scale transistors, discovering new cancer therapies, and creating novel energy harvesting thermoelectric materials.

Education Component: The education plan will motivate students at multiple levels to pursue careers and research in energy conversion and the thermal sciences. New laboratory experiences will be incorporated into undergraduate laboratory courses at the PI's institution. Likewise, a new graduate course in nanotransport will be developed. Teaching kits will be developed for K-12 teachers, and outreach will include summer camps to introduce energy conversion principles to high school girls.


CAREER: Bayesian Models for Lexicalized Grammars

National Science Foundation Award #1053856
Julia Hockenmaier
Computer Science
Project Dates: 02/01/2011 – 1/31/2016

Natural language processing (NLP) is a key technology for the digital age. At the core of most NLP systems is a parser, a program which identifies the grammatical structure of sentences. Parsing is an essential prerequisite for language understanding. But despite significant progress in recent decades, accurate wide-coverage parsing for any genre or language remains an unsolved problem. This project will advance the state of art in NLP technology through the development of more accurate statistical parsing models.

Since language is highly ambiguous, parsers require a statistical model which assigns the highest probability to the correct structure of each sentence. The accuracy of current parsers is limited by the amount of available training data on which their models can be trained, and by the amount of information the models take into account. This project aims to advance parsing by developing novel methods of indirect supervision to overcome the lack of labeled training data, as well as new kinds of models which incorporate information about the prior linguistic context in which sentences appear. It employs Bayesian techniques, which give robust estimates and allow rich parametrization, and applies them to lexicalized grammars, which provide a compact representation of the syntactic properties of a language.

Education Component: This project will also train graduate students in NLP and develop materials that can be used to teach middle and high school students about NLP and to inspire them to pursue an education in computer science.


CAREER: Computational Methods for Analyzing Large-Scale Genomic Changes in Mammalian Genomes

National Science Foundation Award #1054309
Jian Ma
Bioengineering
Project Dates: 03/01/2011 – 2/29/2016

This project will develop new combinatorial and probabilistic algorithms that will unravel the interwoven large-scale genomic changes that have occurred across species in an evolutionary context. The main research thrust is to develop new ancestral genome reconstruction algorithms that handle rearrangements, duplications, and large insertions and deletions at different resolutions in a single unified framework. These methods will be applied to the large number of available whole-genome sequence data to elucidate detailed history of large-scale genomic operations in mammalian genomes. With the reconstructed history, scientists will be able to explain the large-scale genomic changes and assess their phenotypic impact on any lineage, including the human lineage.

These new software tools and resources will shed new light on the extraordinary diversity of mammalian forms and capabilities. Insights from this project will be applied to improve genome assembly methodologies based on next-generation high-throughput DNA sequencing reads. The models and algorithms will also investigate specific genomic regions influenced by large-scale genomic changes, such as complex gene clusters and regions that harbor genome instability in cancer genomes. The open-source software tools for comparative genomics research will be accessible to other scientists around the world. In addition, the outcome of the project will be disseminated through online website. Visualization tools from the research will provide scientific education on genome evolution to increase the accessibility of scientific results to the general public.

Education Component: Educational objectives include new bioinformatics courses; training graduate students with interdisciplinary expertise necessary for the post-genomic era and providing them with meaningful international research experience through collaboration; getting undergraduate students involved in research projects; and participating in the G.A.M.E.S. camp at the University of Illinois to inspire pre-college girls to develop careers in science and engineering.


CAREER: Innovative Confinement Technology for Strong Main Shock-Aftershock Damage Mitigation

National Science Foundation Award #1055640
Bassem Andrawes
Department of Civil and Environmental Engineering
Project Dates: 04/01/2011 – 3/31/2016

This project seeks to mitigate damage and to enhance the robustness and functionality of reinforced concrete bridges subjected to moderate-to-strong earthquakes and their aftershocks. For damage-control, the project will investigate the application of a new concrete confinement technology utilizing the shape memory alloys (SMAs) as the transverse reinforcement. This new technology capitalizes on the concept of active confinement. The research activities planned for this project include: (1) Conducting multi-axial monotonic and cyclic tests on concrete elements confined with the new reinforcement. (2) Developing general 3-dimensional plasticity model for concrete confined with SMA reinforcement with enhanced damage prediction feature. (3) Examining the durability and long-term performance of SMA reinforcement through laboratory tests and field tests conducted on real bridges in Illinois. (4) Developing models for realistic seismic hazard scenarios comprising moderate-to-strong main shock followed by a series of aftershocks. (5) Conducting seismic damage analyses to develop fragility curves for bridges reinforced with the new technology. (6) Conducting confirmatory hybrid simulation tests on reduced-scale reinforced concrete bridge piers strengthened with the new confinement technology.

This project will provide the earthquake engineering community with critical, in-depth, information about the new confinement technology. It will address the modeling, durability, and design issues that are crucial for this technology to reach its full potential in delivering immediate solutions to the problems of post-earthquake functionality, down time, and repair costs of critical lifeline bridges. To increase the awareness of this new technology among the practicing bridge engineers, the PI will organize a workshop to disseminate the project results to this group of engineers. The project will also promote the new hybrid simulation testing technique used in this project to the seismic research community. Finally, this project will also increase the awareness among the research and practitioner communities about the impacts of strong earthquake aftershocks on the design of civil engineering structures.

Education Component: The results of this project will be directly disseminated to the graduate and senior level civil engineering students through two graduate-level concrete design courses taught at Illinois. To encourage and promote the involvement of K-12 students from underrepresented groups in the field of Civil Engineering, an annual summer camp for female high school students will be organized.


CAREER: Investigation of DNA-Binding Protein Dynamics With High-Resolution Optical Traps

National Science Foundation Award #0952442
Yann Chemla
Physics
Project Dates: 02/15/2010 – 01/31/2015

A broad class of DNA-binding protein interacts with the genome in a non-sequence-specific manner. These proteins act mechanically on their substrates, altering DNA conformation by bending, twisting, or stretching the molecule, and oligomerizing to form long filaments. These nucleoprotein complexes often serve as substrates upon which genome maintenance processes occur. Thus, they are involved in all aspects of DNA metabolism, in replication, recombination, and repair, and are important regulators of cellular processes. Single-stranded DNA binding proteins (SSB) serve as a model system for features common to this class of proteins. This project will use a synthesis of techniques from traditional biochemistry and molecular biology, in combination with single-molecule biophysics and computational biology to investigate: (1) how SSBs induce conformational rearrangement of nucleic acids, (2) how they oligomerize into nucleoprotein filaments, and (3) how these protein clusters recruit and modulate the activity of other proteins involved in nucleic acid processing. Specifically, high-resolution optical trapping in combination with single-molecule fluorescence techniques will be used to reveal dynamic protein-DNA interactions, going beyond the limitations of current methods. This work will shed light on fundamental aspects of genome maintenance.

Education Component: The PI has a deep commitment to interdisciplinary education of young scientists and outreach towards underrepresented groups. In particular, he sees in biophysics a unique opportunity to recruit women, who have traditionally been drawn to biology over physics, into the quantitative sciences. The outreach and education components of the project synthesize these themes into a broad plan targeting middle and high school, undergraduate, and graduate education. Specifically, the PI will: (1) develop a lab camp for a girls' summer program to teach middle and high school girls about physics and its impact on biological problems and to provide hands-on experience with biophysics, (2) improve the teaching of an introductory undergraduate physics course for life science students (the majority of whom are women) to better connect physics concepts with biology and medicine, (3) develop a lab course devoted to the training of the next generation of biophysicists in advanced technologies as part of the NSF Center for the Physics of the Living Cells (CPLC), and (4) participate in yearly minority conferences. This project is jointly supported by the Genes and Genome Systems Cluster and the Biomolecular Systems Cluster in the Division of Molecular and Cellular Biosciences.


CAREER: Large-Scale Recognition Using Shared Structures, Flexible Learning, and Efficient Search

National Science Foundation Award #1053768
Derek Hoiem
Computer Science
Project Dates: 05/01/2011 – 4/30/2016

This research investigates shared representations, flexible learning techniques, and efficient multi-category inference methods that are suitable for large-scale visual recognition. The goal is to produce visual systems that can accurately describe a wide range of objects with varying precision, rather than being limited to identifying objects within a few pre-defined categories. The main approach is to design object representations that enable new objects to be understood in terms of existing ones, which enables learning with fewer examples and faster and more robust recognition.

The research has three main components: (1) Designing appearance and spatial models for objects that are shared across basic categories; (2) Investigating algorithms to learn from a mixture of detailed and loose annotations and from human feedback; and (3) Designing efficient search algorithms that take advantage of shared representations.

The research provides more detailed, flexible, and accurate recognition algorithms that are suitable for high-impact applications, such as vehicle safety, security, assistance to the blind, household robotics, and multimedia search and organization. For example, if a vehicle encounters a cow in the road, the vision system would localize the cow and its head and legs and report "four-legged animal, walking left," even if it has not seen cows during training.

Education Component/Dissemination: The research also provides a unique opportunity to involve undergraduates in research, promote interdisciplinary learning and collaboration, and engage in outreach. Research ideas and results are disseminated through scientific publications, released code and datasets, public talks, and demonstrations for high school students.


CAREER: Subsampling Methods in Statistical Modeling of Ultra-Large Sample Geophysics

National Science Foundation Award #1055815
Ping Ma
Statistics
Project Dates: 09/01/2011 – 8/31/2016

Remote sensing of the Earth's deep interior is challenging, and direct sampling is impossible due to extreme pressures and temperatures. Our knowledge of the Earth’s deep interior is thus pieced together from a range of surface observations. Among surface observations, seismic waves emitted by earthquakes are effective probes of the Earth’s deep interior and are relatively inexpensively recorded by networks of seismographs at the Earth's surface. Unprecedented volumes of seismic data brought by dense global seismograph networks offer researchers both opportunities and challenges to explore the Earth’s deep interior. The key challenge is that directly applying statistical methods to this ultra-large sample seismic data using current computing resources is prohibitive. To facilitate geophysical discoveries that can enhance our understanding of the Earth’s deep interior using current computing resources, the investigator proposes a family of novel statistical methods under a subsampling framework to provide an opportunity to study various distinct statistical problems, such as function estimation and variable selection, in a unified framework. The investigator will establish asymptotic and finite sample theory to investigate the approximation accuracy and consistency of the proposed methods.

How to analyze ultra-large sample data creates a significant challenge in almost all fields of science and engineering.Various solutions to tackle the problem include cloud computing for aggregating a wide range of computing resources and powerful supercomputers; however, the high cost of these solutions creates an extraordinary budget barrier for researchers. The proposed subsampling methods provide alternative methods to surmount this challenge. The theory to be established will benefit a wide spectrum of research in science and engineering.

Education Component: This project will offer a unique educational experience for both undergraduate and graduate students to participate in cutting-edge statistical and interdisciplinary research and inspire new lines of research in three distinct fields: statistics, geophysics, and computational biology.


CAREER: Theory and Application of Reflective Microring Resonators

National Science Foundation Award #1055941
Lynford Goddard
Electrical and Computer Engineering
Project Dates: 03/01/2011 – 2/29/2016

The objectives of this program are to characterize, model, and utilize reflective microring reflectors. The PI proposes engineering novel device functionality by integrating a Bragg reflector in a microring resonator. The microring amplifies grating reflection, creating a compact mirror with high reflectivity, narrow linewidth, and no side lobe ripple. These benefits would reduce channel crosstalk and potentially result in lower power, higher data rate communication systems.

The research will advance scientific understanding of the device and demonstrate its potential as a fundamental element to the photonics community. The PI proposes to leverage his preliminary results in device theory, experience in lasers, sensors, and nanofabrication, and experimental capabilities and resources. This potentially transformative research may unlock new lines of research (new devices and models) and enable diverse applications (interferometry, metrology, RF photonics, and communications). Two specific applications will be explored: as cavities for on-chip absorption spectroscopy and as mirrors for tunable lasers.

The broader impacts will be to create novel devices for next generation communications and consumer electronics.

Education Component: Research and teaching will be integrated through the development of two courses: Principles of Experimental Research and Modeling of Photonic Devices. Recruitment, retention, and participation of students from underrepresented groups will be addressed through mentoring, REU internships, and a new electrical engineering summer camp for 10th-12th grade girls. Results from both research and teaching will be published to enhance the current understanding of reflective microring devices and engineering education/outreach methodologies.


CDI-Type II: Collaborative Research: Joint Image-Text Parsing and Reasoning for Analyzing Social and Political News Events

National Science Foundation #1027965
Cheng Xiang Zhai
Department of Computer Science
Project Dates: 10/01/2010 – 9/30/2014

Rapidly changing technologies of multi-modal communication, from international satellite TV, Internet news outlets, to YouTube, are transforming the news industry. In parallel, citizen journalism is on the rise, enabled by smart phones, social networks, and blogs. The Internet is becoming a vast information ecosystem driven by mediated events, elections, social movements, natural disasters, disease epidemics, with rich heterogeneous data: text, image, and video. Meanwhile, tools and methodologies for users and researchers are not keeping pace: it is prohibitively labor-intensive to systematically access and study the vast amount of emerging news data.

The research team is developing a new computational paradigm for analyzing massive datasets of social and political news events: 1) Studying joint image-text parsing to categorize news by topics and events, and analyzing selection and presentation biases across networks and media spheres in a statistical and quantitative manner never before possible; 2) Studying by joint image-text mining to reason the persuasion intents, and modeling the techniques of verbal and visual persuasions; 3) Discovering spatio-temporal patterns in the interactions of multiple mediated events, and analyzing agenda setting patterns; and 4) Developing an interactive multi-perspective news interface, vrNewsScape, for visualizing and interacting with our computational and statistical results.

Intellectual merit: This interdisciplinary project makes innovative contributions to three disciplines. The project develops a data-driven paradigm for transforming communication research in the social sciences. By enabling quantitative studies of massive visual datasets, the research team identifies and characterizes large-scale patterns of news mediation and persuasion currently inaccessible to researchers, due to the prohibitive cost of manual analysis. The research team goes beyond traditional object detection, segmentation, and recognition by studying framing and persuasion techniques in images, an untouched topic in computer vision; semantic associations and meanings for object and scene categories in their social context; and image parsing to fill the semantic gap, a long-standing technical barrier in image retrieval, and will generate narrative text descriptions from the parse trees so they can be fused with the input text and closed captioning for topic mining.

Going beyond conventional topic mining from text to perform integrative text-image mining, bias detection, and pattern discovery in the spatio-temporal evolution of mediated news events, the research detects and summarizes controversy and mine user-generated content for analyzing communicative intent and persuasive effects.

Broader impacts: vrNewsScape is being made publicly available to researchers and graduate students. Because the news media report on events in multiple different expert domains, the analytical tools in development are not limited to a particular research domain but permit a systematic and quantitative examination of the massive datasets required to understand today’s mediated society.

Education: the project extends UCLA’s Digital Civic Learning initiative (dcl.sscnet.ucla.edu), a program involving college and high-school students in the analysis of news, thus delivering education benefits to potentially a huge number of students nationwide in Communication Studies (in 2004, 433,000 college students were enrolled in Communication and Journalism and 209,000 in Political Science[153]), exposing them to a new generation of high-level tools for handling multimodal data and inspiring them to pursue computational thinking, in line with the NSF’s objectives.

  • CMMB IGERT: Training the Next Generation of Researchers in Cellular & Molecular Mechanics and Bionanotechnology

    National Science Foundation Award #0965918
    Rashid Bashir, Martha L. Gillette, K. Jimmy Hsia, Taher A. Saif

    Project Dates: 8/01/2010 – 7/31/2015

    The CMMB IGERT is training the next generation of leaders who will define the new frontiers of cellular and molecular mechanics and bionanotechnology.

    Integrating biology and medicine with micro and nanotechnology can be categorized into two broad areas, namely how micro/nano-fabrication can help solve problems in life sciences (such as diagnostics, therapeutics, and tissue engineering) and how we can learn more from life science to solve important problems in micro/nano-science and engineering (such as bio-inspired self-assembly).


    Collaborative Research: CEDAR—A Novel Technique for Estimating Oxygen Density in the Mid-Latitude Thermosphere

    National Science Foundation Award #0836489
    Lara Waldrop
    Department of Electrical and Computer Engineering
    Project Dates: 7/1/2009 – 6/30/2014

    This project aims to develop an accurate technique for determining the atomic oxygen density in the mid-latitude thermosphere by combining modern instrumentation with state-of-the-art modeling. The method will combine optical and radar measurements to constrain a forward model of a key thermospheric O-atom emission, the twilight airglow at 8446 A, and in turn use the constrained model to develop an [O] estimation scheme suitable for application at other mid-latitude locations. The 8446 A emission has long been considered an ideal candidate for [O] remote sensing owing to its relatively simple emission model, and the project will acquire an unprecedented set of 8446 A spectral data under various observational conditions at two distinct mid-latitude facilities: Millstone Hill (MH) Observatory in Massachusetts and Arecibo Observatory (AO) in Puerto Rico. Additional parameters derived from nested incoherent scatter radar, Fabry-Perot interferometer, and photometer measurements will not only serve as additional forward model constraints, but also help assess the validity of current model assumptions, specifically with regard to the role of secondary sources of 8446 A production. Together with a thorough quantification of model parameter dependencies, the constrained forward model will be used to develop a novel inverse-theoretical technique to estimate thermospheric [O] from measured 8446 A brightness at mid-latitudes. Quantification of neutral atomic oxygen, the dominant constituent in the Earth's thermosphere between 200–600 km, is important for several reasons. In this region, its resonant charge exchange with O+, the principle ion in the F-region ionosphere, plays a vital role in both the momentum and energy exchange between the thermosphere and ionosphere. Similarly, its charge exchange with H+ has long been recognized as an important influence on ion transport between the ionosphere and plasmasphere. Owing to this strong chemical coupling, the accuracy of many fundamental aeronomical calculations—such as the derivation of transport coefficients, neutral wind speeds, energy deposition rates, chemical reaction rates, or photochemical emission brightnesses—hinges on accurate specification of [O]. Thus, current uncertainties in thermospheric composition and density limit the understanding of the coupled thermosphere-ionosphere system, both with regard to its climatological variability as well as its response to impulsive forcing from above and below. The development of a new, ground-based capability of measuring thermospheric [O] will benefit both of these central priorities of the NSF CEDAR program. One graduate student will be trained in this Aeronomy-related area with support from the project. The student will gain familiarity with acquisition and analysis of ISR spectra as well as that of optical SHS, FPI, and photometer data. Available internal funds for undergraduate research support, together with the strong involvement of AO in the Research Experiences for Undergraduates (REU) program, presents another opportunity to introduce undergraduate students to aeronomy as well.


    Collaborative Research: Dimensions: Experimental adaptive radiation-genomics of diversification in bird lice

    National Science Foundation Award #1342604
    Kevin Johnson
    Illinois Natural History Survey
    Project Dates: 11/1/2013 – 10/31/2018

    Adaptive radiation occurs when one species of organism diversifies into several species that occupy distinct ecological niches. The process is a common generator of biodiversity, yet the genetic changes underlying it have not been documented. Parasites, one of the most diverse groups of organisms on earth, are thought to adaptively radiate as they switch to new species of hosts. This process will be studied using birds and feather lice, which are host specific parasites that spend all of their time on the host's body. Lice will be transferred in controlled experiments between normal and novel species of captive hosts. Evolutionary changes in genomes of the lice will be documented as they undergo adaptive radiation.

    The results of this work may have implications for basic research, as well as human and animal health. Genomic data will be deposited in public databases. One postdoctoral associate, two Ph.D. students, and several undergraduate students will be trained. Two educational modules demonstrating adaptation by natural selection will be developed for K-12 students: "cryptic critters" (K-6) and "hunker down" (7-12). These modules are cost effective and easy to implement. Their effectiveness will be assessed with assistance from the University of Utah Center for Science and Math Education.


    Collaborative Research: Physics of Living Systems Student Research Network

    National Science Foundation Award #1026550
    Taekjip Ha
    Physics
    Project Dates: 9/1/2010–8/3/2015

    This collaborative award will support formation of a Physics of Living Systems Graduate Student Research Network, a trans-institutional community-based network of graduate students and graduate student educators all working on the physics of living systems. The initial participating institutions are the University of California, San Diego (which will coordinate the program), the University of Illinois, Urbana-Champaign, Princeton University, Yale University, Cambridge University, and University College, London. The network structure will allow students at participating institutions (and a select number of other students) to meet their peers (both in-person and in-silico) and collectively help define the research agenda for this field. It will also allow for the creation of visiting internships, which will serve both as a way of broadening students perspectives on possible approaches to difficult research topics and as a way of creating collaborative ties between groups at the various sites. This structure will also enable the exploration of various means of educating these students in biology, while also ensuring that they develop and maintain a firm grounding in physics.

    Nanoscale objects, such as metal nanoparticles or carbon nanotubes, are prone to highly efficient absorption of electromagnetic radiation. When high intensity electromagnetic radiation is delivered to such objects, such as by a focused laser beam, the absorbed energy can lead to extreme local heating of and very large temperature increases in both the nanoscale objects and the surrounding medium. These highly localized thermal excursions correspond to heat fluxes that can be orders of magnitude larger than those sustained at the macroscale.

    Intellectual Merit: This research builds upon advances in (a) laser-based ultrafast optical techniques capable of capturing relevant phenomena at pico- to nanosecond time scales and (b) computational power and modeling techniques allowing simultaneous examination of such systems experimentally and theoretically at the same temporal and special scales. In particular, molecular dynamics simulations and time resolved pump-probe experiments will advance the understanding of heat transfer, phase transformation, and phase equilibria arising at the interface between the nanoscale solids and a surrounding liquid.

    Broader Impacts: The research focuses on the exchange of thermal energy between an intensely heated solid nanoparticles and a surrounding liquid. This has important implications for biomedical applications such as highly selective thermal therapy for cancer treatment. Graduate students engaged in the research will make contributions in heat transfer, materials science, soft-hard matter interactions, and phase equilibria. Undergraduate students will also be engaged in the research. Pertinent visual-learning and web-based tools will be developed to integrate the research and education activities.


    Collaborative Research: Variability-Aware Software for Efficient Computing with Nanoscale Devices

    As semiconductor manufacturers build ever smaller components, circuits and chips at the nano scale become less reliable and more expensive to produce, no longer behaving like precisely chiseled machines with tight tolerances. Modern computing is effectively ignorant of the variability in behavior of underlying system components from device to device, their wear-out over time, or the environment in which the computing system is placed. This makes them expensive, fragile and vulnerable to even the smallest changes in the environment or component failures. We envision a computing world where system components—led by proactive software— routinely monitor, predict, and adapt to the variability of manufactured systems. Changing the way software interacts with hardware offers the best hope for perpetuating the fundamental gains in computing performance at lower cost. The Variability Expedition fundamentally rethinks the rigid, deterministic hardware-software interface to propose a new class of adaptive, highly energy efficient computing machines which will be able to discover the nature and extent of variation in hardware, develop abstractions to capture these variations, and drive adaptations in the software stack from compilers, runtime to applications. The resulting computer systems will continue working though components vary in performance or grow less reliable over time and across technology generations. A fluid software-hardware interface will mitigate the variability of manufactured systems and make machines robust, reliable and responsive to changing operating conditions.

    The Variability Expedition marshals resources of researchers at Illinois and other universities. With expertise in process technology, architecture, and design tools on the hardware side, and in operating systems, compilers and languages on the software side, the team also has the system implementation and applications expertise needed to drive and evaluate the research as well as transition research accomplishments into practice via application drivers in wireless sensing, software radio and mobile platforms.

    A successful Expedition will dramatically change the computing landscape. Re-architecting software to work in a world where monitoring and adaptation are the norm will achieve more robust, efficient and affordable systems able to predict and withstand hardware failures, software bugs, and even attacks. The new paradigm will apply across the entire spectrum of embedded, mobile, desktop and server-class computing machines, yielding particular gains in sensor information processing, multimedia rendering, software radios, search, medical imaging and other important applications.

    Education Component: Transforming the relationship between hardware and software presents valuable opportunities to integrate research and education, and this Expedition will build on established collaborations with educator-partners in formal and informal arenas to promote interdisciplinary teaching, training, learning and research. Strong industrial and community outreach ties will ensure success and outreach to high-school students through a combination of tutoring and summer school programs. The Expedition will engage undergraduate and graduate students in software, hardware, and systems research, while promoting participation by underrepresented groups at all levels and broadly disseminating results within academia and industry.


    Critical Zone Observatory for Intensively Managed Landscapes (IML-CZO)

    Intensively managed landscapes, regions of significant land use change, serve as a cradle for economic prosperity. However, the intensity of change is responsible for unintended deterioration of our land and water environments. By understanding present day dynamics in the context of long-term co-evolution of the landscape, soil and biota, IML-CZO aims to support the assessment of short- and long-term resilience of the crucial ecological, hydrological and climatic services. These include freshwater quality and quantity, provision for food, fiber and (bio)fuel, nutrient transformations, and terrestrial carbon storage. The goals of this project are to quantify the fluxes and transformations, as well as interactions, thresholds, and dynamic feedbacks of water, nutrients, and sediment in IMLs, and to characterize how rapid land use changes have altered the vulnerability and resilience of these systems. An observational network of two sites in Illinois (3,690-km2 Upper Sangamon River Basin) and Iowa (270-km2 Clear Creek Watershed), and a partner site in Minnesota (44,000-km2 Minnesota River Basin), which together capture a range of geological diversity of the low relief glaciated and tile-drained landscape in the Midwest, will drive the scientific and technological advances. The guiding hypothesis for the scientific effort is that through human modification, the critical zone of IMLs has passed a tipping point (or threshold) and has changed from being a transformer of material flux, with high nutrient, water, and sediment storage, to being a transporter. This change threatens the resilience of the landscape to accommodate future impacts associated with ongoing human activity, including climate change and bioenergy crop production. Further, it increases the vulnerability of IMLs by compromising the sustainability of key critical-zone services on which ecological systems and human populations depend. Understanding and quantifying shifts in the response of the critical zone to human development remains a challenge, and current assessments are at best qualitative. IML-CZO research will identify threats to resilience of the critical zone, and will also inform management strategies aimed at reducing the vulnerability of the system to human activities that threaten sustainability. We will develop methods and knowledgebase that are broadly applicable across the Midwest and similar low-gradient landscapes worldwide.

    The project will provide leadership in developing the next generation of work force and informing sustainable management strategies. The IML-CZO will be a launch pad for several new educational and outreach initiatives, and it will be an integral resource to connect and partner with existing organizations. It will draw on and add to several resources and programs available throughout the region. The CZO will provide a testbed for student-led sensing and data collection initiatives, and is expected to stimulate new research ideas and further advance the sensors and measurements curriculum. The CZO will also work to bring together collaborations with National Great Rivers Research and Education Center, IOWATER, Minnesota and Illinois RiverWatch Volunteer programs to enlist "citizen scientist" (age 10 - 70) in the work of the CZO. IML-CZO will also serve as a training ground for several undergraduate and graduate students, and post-doctoral research associates by engaging them in interdisciplinary research.


    CPS: Medium: Collaborative Research: Cyber-Physical Co-Design of Wireless Monitoring and Control for Civil Infrastructure

    Project Dates: 10/1/2010–8/31/2014

    The objective of this research is to develop advanced distributed monitoring and control systems for civil infrastructure. The approach uses a cyber-physical co-design of wireless sensor-actuator networks and structural monitoring and control algorithms. The unified cyber-physical system architecture and abstractions employ reusable middleware services to develop hierarchical structural monitoring and control systems.

    The intellectual merit of this multi-disciplinary research includes:

    1. a unified middleware architecture and abstractions for hierarchical sensing and control;
    2. a reusable middleware service library for hierarchical structural monitoring and control;
    3. customizable time synchronization and synchronized sensing routines;
    4. a holistic energy management scheme that maps structural monitoring and control onto a distributed wireless sensor-actuator architecture;
    5. dynamic sensor and actuator activation strategies to optimize for the requirements of monitoring, computing, and control; and
    6. deployment and empirical validation of structural health monitoring and control systems on representative lab structures and in-service multi-span bridges.

    While the system constitutes a case study, it will enable the development of general principles that would be applicable to a broad range of engineering cyber-physical systems.

    This research will result in a reduction in the lifecycle costs and risks related to our civil infrastructure. The multi-disciplinary team will disseminate results throughout the international research community through open-source software and sensor board hardware.

    Education Component: Education and outreach activities will be held in conjunction with the Asia-Pacific Summer School in Smart Structures Technology jointly hosted by the US, Japan, China, and Korea.

    Project Dates: 10/1/2013–9/30/2016

    This cross-disciplinary project brings together a team of engineering and computer science researchers to create, validate, and demonstrate the value of new techniques for ensuring that systems composed of combinations of hardware, software, and humans are designed to operate in a truly synergistic and safe fashion. One notable and increasingly common feature of these "Cyber-Physical-Human" (CPH) systems is that the responsibility for safe operation and performance is typically shared by increasingly sophisticated automation in the form of hardware and software, and humans who direct and oversee the behavior of automation yet may need to intervene to take over manual or shared system control when unexpected environmental situations or hardware or software failures occur. The ultimate goal is to achieve levels of safety and performance in system operation that exceed the levels attainable by either skilled human operators or completely autonomous systems acting alone. To do so, the research team will draw upon their expertise in the design of robust, fault-tolerant control systems, in the design of complexity-reduction architectures for software verification, and in human factors techniques for cognitive modeling to assure high levels of human situation awareness through effective interface design. By doing so, the safety, cost and performance benefits of increasingly sophisticated automation can be achieved without the frequently observed safety risks caused by automation creating greater distance between human operators and system operation. The techniques will be iteratively created and empirically evaluated using experimentation in human-in-the-loop simulations, including a medium-fidelity aircraft and flight simulator and a simulation of assistive automation in a medical context.

    More broadly, this research is expected to impact and inform the engineering of future CPH systems generally, for all industries and systems characterized by an increasing use of hardware and software automation directed and overseen by humans who provide an additional layer of safety in expected situations, Examples include highway and automotive automation, aerospace and air traffic control automation, semi-automated process control systems, and the many forms of automated systems and devices increasingly being used in medical contexts, such as the ICU and operating room. This research is also expected to inform government and industry efforts to provide safety certification criteria for the technologies used in CPH systems, and to educate a next generation of students trained in the cross-disciplinary skills and abilities needed to engineer the CPH systems of the future. The investigators will organize industry, academic, and government workshops to disseminate results and mentor students who are members of underrepresented groups through the course of this research project.


    Cyclogenesis in a Tropical Wave Critical Layer: Vertical Structure of the "Wave Pouch" and Impacts of the Large-Scale Environment

    Project Dates: 9/1/2010–8/31/2014

    This effort will address the genesis of tropical cyclones (and antecedent regions of low pressure and near-surface cyclonic wind patterns termed tropical depressions) through further study of the "marsupial paradigm." This conceptual model refers to a theory of hurricane formation in which the translation speed of one type of parent atmospheric disturbance (termed an "easterly wave") is matched the environmental flow so as to create a protective zone (or so-called "pouch") in which developing small-scale cyclonic circulation(s) are protected from hostile environmental conditions until further strengthening occurs. This study will be supported by data to be collected during the 2010 NSF-supported PREDICT (PRE-Depression Investigation of Cloud-systems in the Tropics) field campaign involving the NSF/NCAR GV research aircraft as well as complementary resources being provided by NASA and NOAA.

    This research will focus on conditions within the meso-alpha scale wave pouch region, its interaction with the larger-scale environment, and impacts of this interaction on ultimate tropical cyclone formation. It will incorporate flight-level, dropsonde and radar data from the PREDICT field campaign, with reanalysis data, various satellite datasets, and the WRF-ARW numerical model to address three main questions:

    1. Is a well-defined wave pouch a necessary condition for tropical cyclone development, and if so, how does it form?
    2. Why do some waves exhibiting a deep pouch fail to develop into a tropical storm?
    3. How does the Saharan Air Layer (SAL) affect tropical cyclogenesis, and why do some wave pouches provide protection from dry air intrusion while others do not?

    The intellectual merit of this effort centers on exploitation of the focused PREDICT dataset in conjunction with numerical model simulations conducted in the marsupial framework to lead to better understanding of tropical cyclogenesis.

    Education: Broader impacts of this research include the education and training of two graduate students and the integration of tools and products into classroom learning activities, as well as support for an investigator drawn from an underrepresented group. Benefits to society will come through the increased understanding of tropical cyclogenesis and associated increases in warning lead time for hurricane formation.


    Discovering the Nanoworld: A New Module for Teaching about Molecules and Bonding in General Chemistry

    Chemistry
    Project Dates: 10/1/2010–9/30/2014

    The objective of this project is to create a new module on the nature of chemical bonding, one of the most fundamental components of undergraduate general chemistry. In place of memorizing rules, the new strategy develops an understanding of the nature of bonding by exploring the process by which atoms combine to form molecules, with an emphasis on developing predictive intuition. Context is supplied by focusing on molecules in real-world situations, such as the gases that constitute Earth's atmosphere. Being developed by expert working scientists and seasoned general chemistry lecturers, the web-based, extensively visual module is being tested in Illinois classrooms and modified in response to student comprehension. The performance of chemistry majors is being tracked through subsequent courses. The module will be improved using input from chemistry lecturers and instructors of later courses that depend upon an understanding of bonding. Instructors are being trained in the new material through local workshops and resources on the website, including video. The website will serve as a nexus for implementing the module beyond the University.

    The way chemical bonding is taught in general chemistry needs to be transformed to update material to reflect current knowledge and address and avoid common misconceptions. Founded on rigorous quantum chemistry, the new module uses both static and animated graphics. Lessons involve discovery of principles rather than rules to be memorized. Employing the same reasoning process working scientists use to study basic phenomena, students will develop their ability to confront the mysteries of the subject and construct an effective cognitive framework for understanding bonding. The approach builds a coherent narrative that connects atoms and their properties to molecules and their properties. It emphasizes connecting theory and its symbolic representations to actual molecules in real-world contexts. This project impacts STEM education by: 1) improving the chemistry curriculum; 2) improving introductory chemistry, which should also help to increase student interest in STEM careers; (3) developing a model for course revision.


    EAGER: Augmented Reality for Understanding Social and Environmental Science

    Project Dates: 5/15/2010–4/30/2013

    This project is an experiment to introduce Augmented Reality (AR) to new platforms. AR is an exciting emerging technology that overlays geographically registered three dimensional computer graphics onto the real world. Until recently, AR required expensive hardware or, at the minimum, a laptop computer equipped with a web camera. Recent improvements in cellular telephone technology, however, have enabled the possibility to use a smart phone as an interaction device for AR, thus creating a portable AR experience. By using the cell phone as a "magic lens," participants can view the real world through the camera on the phone and see the augmentations in place, in registration with the real world.

    In this project, the research team will create a demonstration of how Augmented Reality can aid in understanding and teaching social and environmental science. The interdisciplinary, collaborative team of researchers will develop and demonstrate a sample scenario for using AR environments to teach archaeology at the collegiate level. Archaeology was chosen for a variety of reasons. Archaeology has a very physical component and deals largely with three dimensional objects and, thus, is a good match of needs with the capabilities that AR provides. One problem in teaching archaeology is that the processes and methods of field research are difficult to present in a classroom, and many students will never get the opportunity to engage in field research, and those who do will be limited to only a few different sites. The project team hypothesizes that AR-based simulations will be suitable to expose students to what is involved in field work and to enable them to participate in a wide variety of simulated sites.

    To address the challenge of teaching field work techniques, we seek to create an immersive, interactive demonstration in which students use AR environments to "excavate" sites, interpret artifacts, and create a reconstruction of an overall site. Such an AR environment will include many aspects of actual field work, including excavation methods, strategic analysis (e.g., where to look next), systematic recording of the field data, imaginative reconstruction of 3D artifacts, and interpretation of evidence from multiple sources. Archaeology field work has a considerable amount of physical activity, and the nature of AR is that there is a strong physical aspect to its use. The project team suspects that a smart phone is a suitable interaction device because it is a device familiar to most students and it is of a size such that a student can carry it like any other archaeological tool, such as a trowel or a brush.

    This is a proof of concept project, that AR can be implemented through a smart phone and used in a classroom setting to communicate critical scientific methodologies and concepts, in this case surrounding the discipline of archaeology. However, the implication of this project are quite extensive, e.g., virtual classrooms on small platforms in remote rural communities and field site access to virtual zoological and lithics collections.


    EAGER: Collaborative Research: Exploring the Inverse Cascade in Two-Dimensional Turbulent Soap Films

    Turbulent flows past a wall experience frictional drag, the property of a flow that sets the cost of pumping oil through a pipeline, the draining capacity of a river in flood, and other quantities of practical interest. Much is known about frictional drag, mostly from extensive experiments in which frictional drag was measured in pipes or open channels; yet, there has been no known link between frictional drag and statistics of turbulent eddies in the flow. The project's goal is to test experimentally a recently proposed theory that will allow us to predict frictional drag from a knowledge of the statistics of turbulent eddies. This will be achieved through measurements in a type of two-dimensional turbulent flow that may be realized in very thin soap films, where it is possible to create flows with different types of statistics. If confirmed, the theory could provide the key to understanding the drag-altering effects of polymeric additives used in oil pipelines, particulate suspensions found in rivers in flood, entrained bubbles found in water-treatment plants, and other agents known to affect the statistics of the flow. At Illinois and Pittsburgh, graduate and undergraduate students will be trained with a multidisciplinary focus encompassing engineering and fundamental condensed matter physics, introducing undergraduates and women to research in turbulence. The PIs will collaborate on outreach to grades 6-12, work with an all-girl's middle school to devise a unit on soap film physics, turbulence, chaos and optics, and participate in a teacher's workshop.

    Project Dates: 6/01/2009–5/31/2014

    The Mathematics Department at illinois aims to train stewards of the mathematical enterprise. Our programs facilitate all stages of development from prospective undergraduate math major to senior mathematician. We propose here to enhance our REGS program and thereby impact several critical transitions at the graduate level. REGS stands for Research Experiences for Graduate Students”; for many students, REGS provides the initial contact with research. Our current program provides summer support for early graduate students to work (individually or in a group) on a research project with one or several faculty mentors. We propose here an enhanced program with four components: one for incoming Ph.D. students (REGS 0), one for 1st- and 2nd-year Ph.D. students (REGS 1), one for students who have already begun thesis research (REGS 2), and one for students about to complete their dissertations (REGS 3). The first three components are summer programs, while the fourth provides a year-long fellowship. We will extend the reach of our programs by including external participants in the REGS 0 and REGS 1 components. The external participants will include students from underrepresented minority groups and also from schools which do not have mathematics Ph.D. programs.

    This project addresses a documented and persistent problem in introductory physics instruction: Students taking introductory physics are loath to read the textbook prior to coming to class and are unprepared to participate in classroom activities aimed at refining conceptual understanding and promoting problem-solving skills. The project's Multimedia Learning Modules (MLM) for the two-semester, calculus-based introductory physics course incorporate established learning principles from research on multimedia learning by combining animated video with accompanying audio to engage students' auditory and visual working memories, which improves their mastery of the material. The MLM teach basic conceptual knowledge and are used with Just-in-Time Teaching (JiTT) to improve students' pre-class preparation, thus freeing up class time for other uses.

    The impact of the MLM on learning are evaluated by developing a set of questions that are administered to students prior to coming to each lecture both before and after the MLM are implemented, and by comparing performance on secure final exams both before and after implementation of the MLM. The materials are also being tested at partner institutions that have a very dissimilar student demographic profile from the students at the University of Illinois at Urbana-Champaign.

    This project is transforming a course to capitalize on the diversity of the students enrolled in the course and to incorporate course content of immediate interest to students. This new classroom pedagogy, called diversity harnessing, folds the direct interests of the student population back into course materials through lecture topics, homework exercises and exam problems. Diversity harnessing is making extensive use of active and collaborating learning. The course, ECE 101: Exploring Digital Information Technology, is an engineering course for non-engineering majors that strives to prepare students for a meaningful role in an increasingly technological society. The goals of this project are to 1) better engage the students in the course topics, 2) quickly integrate diverse student-driven subject matter back into the course, and 3) empower the students to more effectively apply new skills to their lives and careers. The project includes rigorous formative and summative evaluation plans with both qualitative and quantitative components coordinated by an independent evaluator.

    The project explores the mechanism of VLS (vapor-liquid-solid) planar III-V nanowire growth. It addresses basic research issues in a topical area of materials science with technological relevance. Results from the proposed research will be incorporated in the syllabus of a new course the PI is teaching on Semiconductor Nanotechnology. A semi-annual Student Research Symposium on Semiconductor Nanotechnology led by the PI will serve the dual purpose of dissemination of research results and training of students in public speaking and scientific presentation, The interdisciplinary nature of the project reflects materials science, electrical engineering, chemistry and physics, with potential technological impacts in electronics and photonics. By engaging students in such integrated research and education, the competence and leadership of our future workforce will be enhanced. By recruiting and retaining women engineers through creating and maintaining a sense of community and leading by example, the PI seeks to make a long lasting effect on the education and training of a broadly inclusive science and technology workforce. The outreach component of the project targeting elementary school girls will expose more young minds at a timely stage about the interesting challenges and opportunities in science and engineering careers.

    It has been recognized recently that materials subjected to SP often possess excellent properties for use in extreme environments; they have very high strengths and they tend to be resistant to damage by energetic particle irradiation, such as in a nuclear reactor. The goal of this research is to provide the scientific basis for processing nanocomposite structures and how to design them with properties tailored to specific applications. The mechanism by which atoms intermix and randomize during SPD is analogous to shaking a vial of oil and water, which are normally immiscible - oil floating on top of the more dense water. When the vial is shaken, the interface between the two at first roughens, and as the intensity of the shaking increases, small globules of water form in the oil and vice-versa. The sizes of the globules decrease with the intensity of shaking until finally a homogeneous emulsion is obtained. The intermixing of two immiscible metals during SPD and the length scales and patterning of the "globules" of solid phases in the newly formed nanocomposite materials are of primary interest. The proposed research has broad scientific impact for developing design strategies for new nanocomposite materials that are critical to a number of advanced materials applications: hydrogen storage, batteries, radiation-resistant nuclear materials, etc. In addition to disseminating our research through publications and scientific meetings, educational demonstrations of these new materials will be developed for the "Materials Mobile" at UIUC which introduces concepts of materials science and engineering to high school students around the State of Illinois.


    GOALI: Validated Multiscale Simulations of Ceramic Matrix Composites for Power Generation

    Project Dates: 9/15/2010 – 8/31/2014

    The objectives of this Grant Opportunity for Academic Liaison with Industry (GOALI) research project are to improve the understanding and to model the failure mechanisms of CMCs using an integrated approach based on novel multiscale computational methods and experimental validation. Revolutionary design of future power generation systems, rockets, and most recently, hypersonic missiles and flight vehicles are contingent on the development of advanced materials like ceramic matrix composites (CMCs), able to operate at high temperatures. A major challenge in the design of CMC components is the determination of the fracture behavior of these materials at relevant crack sizes for ceramic materials. Fracture of CMCs involves phenomena spanning several spatial scales from micron-size fibers to meter-size structural components. Illinois will collaborate with researchers and engineers from General Electric Company to vigorously expand fundamental knowledge and modeling of damage mechanisms in CMCs.

    This research offers an alternative for the difficult and costly fracture experiments needed to determine the fracture behavior of CMCs. If successful, it will allow validated simulations and improve the understanding of complex multiscale phenomena. This will pave the way for the solution of important engineering and scientific problems. While the focus of his research is on the problem of failure of CMCs, this multiscale framework may also have a direct impact on the modeling and understanding of other material systems and problems where existing multiscale methods are not applicable.

    Education Component: This research program will enable the education and training of graduate and undergraduate students from Illinois. These students will be involved in a multidisciplinary research topic that will foster critical interactions with researchers and engineers from General Electric Company. Another objective of this program is to motivate K-12 students to pursue an engineering degree. This will be achieved through the hands-on seminar Computational Mechanics, Engineering and Simulation Showcase (COME-&-SEE), showcasing the environmental and economical impact of computational engineering sciences.


    Graduate Assistance in Areas of National Need (GAANN) Program

    U.S. Department of Education Award #P200A090308
    Steven Zimmerman
    Chemistry

    Our nation’s future economic, military, political, and moral vitality depends on its ability to educate its own citizens and permanent residents to assume leadership roles in the fields of science, mathematics, and engineering. Among these, chemistry is a specific area of national need identified by the Secretary of Education. Therefore, the Department of Chemistry's Graduate Assistance in Areas of National Need program promotes the following objectives, to:

    • Mentor graduate fellows who are committed and talented educators to become leaders in the intellectual development of the field of chemistry.
    • Train graduate fellows to be technically preeminent chemists in all aspects of the discipline.
    • Train the next generation of chemists in the traditional areas of chemistry and, in particular, the new, emerging areas of the field, chemical biology and materials chemistry.
    • Join the vanguard of a curriculum reform that reflects the evolution of chemistry in the 21st Century.
    • Build on a long tradition of inclusion and integration of underrepresented groups in the Chemistry Program at Illinois.

    The GAANN Chemistry Fellowships are primarily to recruit and retain new graduate students from historically underrepresented groups. Fellow selection includes an outstanding academic record, intellectual promise, and demonstrated financial need. A unique feature of our teaching program is a three-tiered, vertically integrated teacher-mentor system. The system links undergraduates in our highly successful Merit Program with beginning GAANN fellows who serve as instructors and mentors. Merit seeks to recruit, retain, and foster the academic success of traditionally underrepresented undergraduate students. The presence of GAANN fellows as Merit Workshop facilitators provides role models for undergraduates while also enriching fellows’ teaching experience. As GAANN fellows advance in the Ph.D. program, they serve as formal and informal mentors and tutors of beginning GAANN participants. All interactions build a support network, increasing retention and academic achievement at all levels. A key underlying program theme is that true gender and racial equality in the field of chemistry will not be achieved until the “pipeline issue” is solved: women and underrepresented minorities must obtain Ph.D. degrees from top chemistry programs and in proportion to their representation within the population.

    Dates: August 1, 2009–July 31, 2015 (estimated)

    This Integrative Education and Research Traineeship (IGERT) project will educate a diverse cadre of neuroscientists and engineers at the University of Illinois with an advanced understanding of both neuroscience and engineering, enabling them to engage in both sophisticated collaboration and independent research across the traditional gap between these domains. Many of the most important and exciting scientific and technological challenges for the future are centered on neuroscience, the study of the brain. Many recent (and most future) advances in understanding the brain depend on engineering new technologies for sensing, imaging, and analyzing the brain and their innovative use by neuroscientists. Similarly, some of the greatest and most important technological challenges, such as creating neural prostheses for the disabled, require engineers with a profound understanding of neuroscience. IGERT students will thus carry out innovative interdisciplinary research on neuroscience areas of great scientific and engineering importance, such as speech and audition; brain and imaging; neural implants that may lead to revolutionary advances in understanding the brain; and in new technologies, such as neural prostheses for the disabled. IGERT trainees will also receive training in leadership, communication skills, and the responsible conduct of research, as well as preparation for academic or industrial careers.

    This goal of this Integrative Graduate Education and Research Training (IGERT) award is to create a graduate training program that will produce the next generation of intellectual leaders in Cellular & Molecular Mechanics and Bio-Nanotechnology. This program represents a highly coordinated and interdisciplinary effort to educate Ph.D. students across the University of Illinois at Urbana-Champaign, University of California at Merced, North Carolina Central University, and partner institutions to tackle the important problems in bionanotechnology spanning the molecular-cellular-tissue scale.

    How living cells transduce mechanical signals to functionalities at different length scales, from inside cells to their communication with the extra cellular matrix, presents a scientific grand challenge of our times. Recent advancements in micro/nanotechnology, molecular scale imaging, and computational methodologies will catalyze this quantitative biological revolution at a cellular and molecular scale. Students who have been trained at the intersection of these domains have the potential to revolutionize tissue and regenerative engineering, biological energy harvesting, sensing and actuation, cells-as-a-machine, and synthetic biology, to name a few. Unique training efforts in this program include a two-track educational program to educate engineering and biology students to develop depth and breadth in their area of research, new experimental modules and a summer workshop introducing the IGERT trainees to state-of-the-art equipment and laboratory procedures, an exciting iWORLD program with collaborators around the world that will provide IGERT trainees with international research experiences, and a student leader council that participates in the leadership and drives the management of the IGERT.

    IGERT is an NSF-wide program intended to meet the challenges of educating U.S. Ph.D. scientists and engineers with the interdisciplinary background, deep knowledge in a chosen discipline, and the technical, professional, and personal skills needed for the career demands of the future. The program is intended to catalyze a cultural change in graduate education by establishing innovative new models for graduate education and training in a fertile environment for collaborative research that transcends traditional disciplinary boundaries.

    Dates: February 1, 2011–January 31, 2016 (estimated)

    The Center for Agricultural Biomedical and Pharmaceutical Nanotechnology (CABPN) will focus on developing nanotechnology platforms that can be applied to three substantially important topics requiring strong industry/academic partnerships: Agriculture, Pharmaceutical Research, and Biomedical Applications. The proposed center will be a single-university center located at the University of Illinois at Urbana-Champaign (illinois).

    The proposal touts advances in health care and agriculture at the confluence of biotechnology and nanotechnology in a "convergence of frontiers." The emphasis will be on taking bio-nanomedical developments from the bench to benefit agriculture and healthcare. Advances in this center are anticipated to enhance the development of vaccines for food animals, and safety of the food supply, monitoring patients in intensive care and tools to make pharmaceutical research more effective. The proposed center will enable assembly of a cohesive University0Industry alliance that will enable Industry participants to communicate their research needs to academia, to facilitate collaboration between companies in different market spaces, and to train graduate students as effective future leaders.

    Fostering cooperation between the hard core nanotechnology practitioners (mostly coming out of electronics and materials departments) and those in agriculture, biomedicine, and pharma could provide a cross-discipline platform on which to stir the intellectual melting pot and generate innovative solutions. Should CABPN succeed in transitioning the tools of nanotechnology to commercial use in these unrelated fields while gaining synergies from their interaction at the center, it could be a real driver for commercial innovation. Success could produce jobs and improve the life of the nation.

    Education/Dissemination: CABPN has planned an active role in mentoring students and has incorporated them into its overall plan. The proposed Center has a system for outreach to minorities to foster training in nanotechnology to the widest group of individuals possible, and plans to have meetings within the I/UCRC framework to widely disseminate the technologies within the staff of the I/UCRC as well as partnering organizations. Publication of works is also planned and the PI has a path to publication that takes into account the commercial interests of the partner organizations.

    Psychology

    Dates: July 1, 1997–June 30, 2014 (estimated)

    The continuing training program in language processing trains scientists who can advance our understanding of the cognitive basis of human communication. For predoctoral trainees, the program offers a coherent set of formal courses, advanced-topics research seminars, and research training in experimental and developmental psycholinguistics, linguistics, and computational modeling. For postdoctoral trainees, the program offers opportunities for broadening knowledge and skills, especially in preparation for careers in linguistics or cognitive neuroscience. For students at all levels, the program offers broad and balanced training as scaffolding for the development of outstanding researchers. The research of the program faculty spans language acquisition, language production, language comprehension, and linguistics. This breadth fosters abilities in conceptual analysis and theoretical development across the full range of core components of human language use. The methodological expertise of the program faculty encompasses eye-movement monitoring, computational modeling, event-related-potential recording, optical and functional-magnetic imaging, articulatory tracking, corpus analysis, speech analysis, and the basic techniques of cognitive and developmental research. This range gives trainees the opportunity to attain high levels of skill in designing, implementing, and interpreting experiments using state-of-the-art methods for probing the workings of language. Funds are requested to support four predoctoral and two postdoctoral trainees per year. The predoctoral training program demands four years beyond the bachelor's degree. It fulfills the basic requirements for the doctoral degree within the cognitive or developmental divisions of the Department of Psychology, using division options to create doctoral-program plans with a major emphasis on the experimental study of language processing and acquisition and minor emphases on linguistics, cognitive neuroscience, and speech processing. The postdoctoral program offers training in language processing and acquisition as a supplement for doctoral training in linguistics or cognitive neuroscience. The proposed training will take place within a strong institutional matrix formed by the Cognitive and Developmental Divisions of the Department of Psychology and the Cognitive Science Group at the Beckman Institute for Advanced Science and Technology. Both settings offer exceptional physical and intellectual resources fueled by a rich tradition of graduate training in psycholinguistics. The program develops expertise in basic research on human communication. This research addresses the emergence of communicative abilities in infants and children, problems of human communication, methods for enhancing human communication, and disorders of human communication.


    Microscopic Theory of Many-Particle Systems from Nuclear Physics to Cold Atoms

    Dates: September 15, 2010–August 31, 2015 (estimated)

    This award continues an ongoing program to develop fundamental theories of many-particle systems, ranging from nuclei and nuclear matter to cold atoms, with applications to astrophysical and condensed matter systems. A major focus is on understanding new states of matter formed under extreme conditions, especially quark gluon plasmas produced in ultrarelativistic heavy ion collisions. The program applies nuclear theory to neutron stars and supernovae, with the aim of understanding observations and, conversely, using observations to learn the properties of matter. The research on atomic Bose-Einstein and superfluid Fermi systems, a vital facet of the study of unusual states of matter, focusses on atomic states at low temperature, as well as under extreme rotation. This research also makes important interdisciplinary connections between ultracold atomic systems and dense nuclear matter. The nuclear and atomic systems being studied are very unusual many-particle systems which provide broad intellectual insights. By working across the boundaries between nuclear and atomic physics this program enables the building of bridges and cross-fertilization between the hottest and coldest many-particle systems in the universe.

    Education Component: A vital component of this research program is the education of young scientists who, through the broad training they receive and their intimate involvement in the research of the PIs and colleagues, develop the ability to combine nuclear, particle, astro, condensed matter, and cold atom physics research on forefront problems. The scientists trained in this program have generally gone on to have significant impact in research at U.S. universities and national laboratories, as well as abroad.

    Non-destructive and non-invasive imaging in three dimensions allows for the analysis of intact samples of a diverse nature. Several techniques are available for 3D imaging from the atomic to macroscopic scales but are limited in their ability to probe complex materials. Confocal Raman microscopy provides a non-invasive and non-destructive method for 3D imaging of challenging samples and is required for the advancement of several projects, providing a platform for optical and spectroscopic analysis in materials characterization. Configured to allow for diversity in sample handling, the instrument will support a broad range of ongoing Illinois research programs in more than 18 different laboratories. Key research areas have been identified that would greatly benefit from acquisition of this advanced instrument including self-healing systems, multi-functional polymers, electronic materials, and cells & tissues. The instrument has relevance in a diverse array of research at Illinois and will be housed at the Microscopy Suite of the Imaging Technology Group at the Beckman Institute for broad access across campus. This instrument will be the only multi-user-accessible multi-wavelength confocal Raman microscope on campus.

    Education Component:The Imaging Technology group and collaborating faculty will continue to enhance science education and training through a variety of outreach projects for a diverse group of students and staff.

    Emerging trends suggest that a significant share of Internet traffic will be due to real-time streaming applications. However, given the unpredictable nature of popularity of any content and the significant swings seen in user demand, provisioning a centralized content distribution system that can guarantee the strict quality of service constraints needed for real-time streaming is a very difficult task. Therefore, this project studies modeling paradigms and systems design for utilizing end-user resources for real-time streaming in a peer-to-peer (P2P) fashion. The rationale is that P2P networks can dynamically adapt to changing network conditions and service requirements more easily than centralized content distribution systems.

    This research effort takes a holistic approach in which, on one hand, we study fundamental performance limits of peer-to-peer streaming and design distributed algorithms to achieve these limits. On the other hand, we use these algorithms as building blocks to construct practical protocols that are implemented and validated on an emulation testbed. We bring together a rich set of analytical tools drawn from stochastic processes, optimization and control theory to merge them with real-life multimedia issues of video coding, frame dropping and trans-coding as well as practical implementation issues. Besides the technological impact of developing viable video-streaming ideas for an increasingly networked world, our project also informs and educates both students and the broader society with curriculum development, outreach and integration of under-represented groups.


    NeTS: Small: Scaling Routing: From Theory to Practice (and Back Again)

    Traditionally, networks are scaled to very large size through hierarchy: routing is performed on higher level aggregates and subsequently at finer granularity. The consequences are inefficiency in the form of inflated path lengths, and the use of location-dependent addresses which complicate management, mobility, and multihoming. Routing on location-independent "flat names" can solve these problems and is independently useful to support secure, self-certifying identifiers. But no previously proposed protocols exist for scalable, efficient routing directly on flat names. This project is developing distributed compact routing (DCR) protocols which route on flat names while guaranteeing scalability and efficiency for arbitrary networks. Building on recent theoretical advances in the area of compact routing, DCR addresses key challenges including autonomous distributed operation, congestion, and heterogeneity. The project is applying these techniques to Internet routing, mobile ad hoc networks, and content-centric networks. In addition, the project is studying recent systems-oriented proposals to scale Internet routing based on separating the "core" of the Internet from the edges, providing firm theoretical footing by determining when they can improve scalability with little loss of network efficiency. The results of this project will significantly improve scalability, mobility, and manageability in the Internet and other networks, bridging a gap between promising theoretical results and emerging practical needs. Results will be disseminated through publications and presentations, a public software release, and graduate and undergraduate courses.

    In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Steven Zimmerman of the University of Illinois will create a practical system of nanoscale adhesion promoters using the tools of supramolecular polymer chemistry. The approach is to further expand the toolkit of multiple hydrogen bonding units, and to develop general methods to functionalize polymers and surfaces with such units. The ability of the adhesion promoters to adhere two surfaces together at the macro-, micro- and nanoscopic levels will be assessed as will the reversibility and self-healing nature of the attraction. The broader impacts involve training undergraduate students, graduate students and postdoctoral researchers, broadening participation through the inclusion of women researchers on the project, and continuing to build a summer bridge program for URMs at the University of Illinois, Department of Chemistry.

    This work will enhance our fundamental understanding about polymer adhesives and composite materials. Adhesives and composite materials have improved human life in innumerable ways, for example, the latter being found in a broad range of high performance products such as aircraft, Hummvees, and the Space Shuttle. There is a significant need for more advanced materials, including reversible glues, and composites with greater strength and resistance to delamination. For example, the fracturing of a composite material is what precipitated the Shuttle Columbia disaster. The results of these studies could have many important long term impacts on applications in which engineering adhesives are important, including automotive, packaging, and aerospace industries.


    NetSE: Large: Collaborative Research: Exploiting Multi-Modality for Tele-Immersion

    Dates: October 1, 2010–September 30, 2015 (estimated)

    Providing an environment that offers both immersion and interaction is a tough research challenge. Ensuring a reasonable Quality of Experience (QoE) in using these environments installed in geographically distributed cities is even a tougher challenge. This project considers a collaborative, immersive, and interactive environment that not only supports 3D rendering of the participants’ video but also other modalities such as Body Sensor Network (BSN) data that can offer highly precise data about a person’s physical movements (as well as physiological data). While creating this environment, one needs to consider the various bottlenecks that choke the data streams carrying the immersive and interactive information: reconstruction delay, ultra-high throughput needed, packet loss, and rendering delays.

    The main aim of this project is to design and develop collaborative, multi-modal immersive environments with higher frame rates and frame quality by carrying out research tasks that can take advantage of information from other modalities and handle these bottlenecks.

    In a typical tele-immersive environment, participants can see themselves in the locally rendered 3D view and see participants in the remote environments as well. Since local rendering delays are much smaller, participants can see themselves earlier and in a more smooth fashion compared to the rendering of remote participants that suffers from communication delays and packet losses. This aspect of varying delays among the immersive participants can potentially cause problems during dynamic interactions and affect their QoE. Answers to questions such as what type of problems can be caused and how the participants handle them depend on the application domain of the immersive environments. To study the QoE and validate (with usability studies) the collaborative, immersive environment, a tele-rehabilitation application will be deployed in multiple cities: Berkeley, California; 2 sites in Dallas, Texas; and Urbana-Champaign, Illinois.

    Intellectual Merits: (i) The resource adaptation framework for streaming multi-source, multi-destination, multi-rate, multi-modal data incorporates supervisory hybrid control theory based fine-grained resource management, multi-modal coarse-grained management, and a multi-modal multicasting approach. (ii) Graphics Processing Unit (GPU)-based 3D reconstruction and compression algorithms. These algorithms facilitate reconstruction of 3D data points based on 3D camera array data and compress them at a faster pace than their CPU-based counterparts. (iii) GPU-based rendering algorithm of 3D data on the receiver side. This algorithm will handle potential data loss in 3D camera data streams using skeletal information from BSN data streams. (iv) Identification and measurement of Quality of Experience (QoE) metrics and using those metrics to derive Quality of Service (QoS) parameters. The derived QoS parameters will then help the resource adaptation framework to modify its decisions at run-time. This project aims to have transformative aspects in the new set of algorithms that exploits multi-modality while incorporating a feedback based on Quality of Experience for functions such as streaming, 3D reconstruction, and rendering.

    Education Component: This project promises significant impact in the fields of education and pervasive health care by providing augmented abilities to carry out intricate programs such as tele-rehabilitation with increased correctness and flexibility. This can also lead to improved productivity in the society considering the ability of health-care professionals to potentially handle a larger population (in remote places) as well as considering the possibility of the affected persons to become independent and productive faster. The project also ensures the results from the proposed research will be incorporated into the courses being taught. 3 women PhD students and 6 under-graduate students (2 are minority students) already working with the investigators of this project. Serious efforts will be undertaken to continue their involvement in this project. Apart from refereed conference and journal publications, the developed software, collected data, and research results will be shared with other researchers through a dedicated website (after ensuring satisfaction of HIPAA regulations).

    The primary goals of this Children's Center are to use a multidisciplinary approach to address critical gaps in our knowledge about the impact of exposure to endocrine disrupting chemicals (phthalates/BPA) on child development, to actively involve junior investigators in this research effort, and to actively communicate our research findings to parents, childcare providers and healthcare providers. There are three common themes that unite the three research projects and the Outreach and Translation Core (COTC) of this Center: (1) assessment of exposures during two critical developmental windows (prenatal and adolescent), (2) investigation of joint effects of phthalate/BPA exposure and a high fat diet/obesity, and (3) investigation of the role of oxidative stress and inflammation in mediating effects. At the heart of the research effort will be two human cohorts (Project 1)-a prospective pre-birth cohort currently in progress in Urbana, Illinois and an adolescent cohort to be assessed as part of a long-standing prospective study in New Bedford, Massachusetts. The Center will also include laboratory animal projects (Projects 2 and 3) which will model the timing of exposures in these human cohorts, a COTC, and this administrative core which will provide oversight, coordination and integration of all Center-related activities. The responsibilities of the Administrative Core will include organizing and scheduling monthly meetings of the Internal Advisory Committee and monthly research team meetings of the Center investigators, organizing yearly meetings of the Center scientists with the six-member External Advisory Committee, coordinating the career development activities of the Center, and facilitating interactions of the Pediatric Health Specialist with the COTC to communicate research findings to the healthcare community. As Director and Associate Director of the Children's Center, Drs. Susan Schantz and Jodi Flaws will be responsible for conducting Internal and External Advisory Committee meetings and regularly evaluating the research progress of each of the projects, as well as the outreach activities of the COTC. They will also be responsible for general fiscal oversight of the Center. Dr. Flaws will have full authority to make decisions in Dr. Schantz's absence. Relevance: Phthalates and BPA are endocrine disrupting chemicals that are found in many consumer products. Exposure is widespread, but the impact of this exposure on child health and development is not well-understood. This Center's research will fill an important gap in our knowledge by investigating the effects of these chemicals, both alone and combination with a high fat diet on reproductive and neural development.

    The STC on Emergent Behavior of Integrated Cellular Systems (EBICS) will develop the science and technology needed to engineer clusters of living cells (biological machines) that have desired functionalities and can perform prescribed tasks: sensing, information processing, actuation, protein expression, and transport elements that can be effectively combined to create functional units. These biological machines could perform tasks such as processing systems that detect toxins in the environment and neutralize them; smart plants that sense and respond to the need for water and nutrients, surrogate organs that are used in place of animals to test new drugs; and biological factories that sequester CO2 in a continuous flow process.

    This STC in engineered biological systems seeks to understand how cell systems interact to produce coordinated, emergent behavior under the control of local micro-environmental cues consisting of biochemical factors and physical stimuli. Single-cell machines or factories hold enormous promise, but multi-cellular systems that incorporate populations of specialized cells assembled into a single integrated unit could have greater impact. New understanding of cell-cell and cell-matrix interactions is critical and will require new technological platforms to bridge molecular scale interactions with macroscale behavior of complex biological systems. The proposed research is truly transformative and revolutionary at the interface of science and engineering. EBICS has the potential to enhance understanding of emergent biological behaviors under integrated biochemical and physical cues at the cellular, cell network, and cell population levels.

    Education Component: The outreach and knowledge transfer program seeks to attract more young students into STEM, particularly into the interdisciplinary field of bio-engineering. The Center’s alliance/collaborative research plans with minority-serving institutions will improve participation of underrepresented minorities in STEM. The two-track, integrated graduate program merging the essential sciences and technologies will offer a graduate teaching consortium to offer courses synchronously in all partnering institutions via the internet and international experiences by internships. Graduate courses developed by EBICS will be recorded and made widely and freely accessible through OpenCourseWare. The novel and revolutionary nature of the research will attract the best and the brightest students into this program and strengthen the future US workforce’s global competitiveness. The Center’s potential discoveries could potentially impact critical national needs: energy, the environment, security, and healthcare.

    In the Center for the Physics of Living Cells (CPLC) experimentalists, computational physicists, and theorists will jointly attack the extreme technical challenges posed by quantifying processes in living cells with the sensitivity needed to explore how life organizes itself, weaving molecular systems into the fabric of living matter. Specifically, the Center will: (1) push in vitro single molecule techniques to a 10- to 100-fold increase in sensitivity, spatio-temporal resolution, and throughput for concurrent detection of multiple observables; (2) use synthetic nanostructures to manipulate single molecules, enabling measurements of both forces and molecular conformation with sub-microsecond resolution; (3) observe individual events within single cells, enabling time- and space-resolved studies of gene expression and other key cellular processes; and (4) extend computation to biologically relevant timescales, and theory to greater biological realism, enabling the detailed interpretation of the dynamics of biological systems from the molecular to the cellular level. The interaction between theory, computation, in vitro and in vivo experiments will be at the core of the Center's mission. A concrete example combining these four approaches will be to build a truly quantitative and dynamic physical picture of transcription and translation machinery used by the cell to copy DNA into RNA and then into proteins.

    The Center will provide exciting educational opportunities on and off campus. For Ph.D. students, the Center will build a community around special seminars, symposia, tailored courses, and joint mentoring and help generate a new generation of scientists who are fluent in both physics and biology. This new science will be brought to the undergraduate level in the form of courses, online computing and visualization environments, and a single-molecule laboratory course where they can acquire hands-on experience. The Center will recruit minority students into the REU programs and summer workshops through partnership with primarily minority institutions and participation in two annual scientific meetings for under-represented minorities. At the high school level, the Center will expand an existing programs in which Ph.D. students can act as mentors for teachers on and off campus, introducing visualization tools and modern molecular biology concepts into the classroom. To address young students directly, the Center will establish a pilot program at a girls' middle school. This program will provide contact with students as they begin their formal science education, exposing them to modern biophysical concepts and tools. To the scientific community, the Center will provide visualization and simulation tools to enable the study of macromolecular assemblies and cells. Likewise, the state-of-the-art instrumentation developed by the Center will lead to mainstream applications in biological sciences and is expected to have major commercial impact.


    Photonic Crystal Enhanced Microscopy for Characterization of Cell Attachment

    National Science Foundation Award #1132301
    Brian Cunningham, Lawrence Schook
    Micro and Nanotechnology Lab

    Dates: September 1, 2011–August 31, 2014 (estimated)

    This project is developing a photonic crystal enhanced microscope (PCEM) as a powerful multimode imaging approach for quantification and visualization of the interactions between cells and surfaces. The PCEM is designed to utilize the properties of a photonic crystal (PC) biosensor surface that is designed to produce narrow bandwidth optical resonances.

    Broader Impacts: Biologists are developing a more sophisticated understanding of how cell membrane interactions with surfaces, chemical stimuli, and other cells are modulated, and the role of integrins, ion channels, G-coupled transmembrane proteins, and filapodia in fundamental processes such as migration, wound healing, differentiation, and apoptosis. Yet, there are few tools currently available that allow visualization and quantification of these processes. While the initial set of demonstrated applications for PCEM will include cancer cell cytotoxicity, T-cell induced apoptosis, stem cell differentiation, and cardiac cell stimulation, the system's capabilities extend to any cell type and any process that can be carried out upon a surface.

    Education Component: The system will be included in multidisciplinary training programs. Users of the system will be comprised of faculty, graduate students, and undergraduate students from Engineering, Pharmacology, Animal Sciences, Microbiology, and Immunology. The project will develop general-purpose methods for studying cell-surface interactions that can be used broadly in pharmaceutical screening and life science research - extending the applicability of photonic crystal biosensors. The PI has a successful track record of biosensor instrumentation invention, development, and commercialization. The proposal also describes an education plan that is closely linked with the program's technical goals with impact upon graduate student research, undergraduate research, undergraduate classroom/laboratory learning, and teaching biosensing/photonics concepts to a University-based all-girls middle school. The PI has a strong track record for involving undergraduate students in his research, and for making the technology developed under NSF funding available in his ECE416 "Biosensors" course, both in the form of lecture topics and hands-on laboratory experience.


    Plasticity and Avalanches: Connections Between Systems Ranging from Metals to Granular Materials

    National Science Foundation Award #1005209

    Physics

    Dates: October 1, 2010–September 30, 2014 (estimated)

    This award supports theoretical research and education to combine concepts from statistical physics, materials science, solid mechanics, engineering, granular mechanics, and metallurgy to advance and unify understanding of how materials respond to external stresses.

    Many systems crackle when they are pushed slowly: Wood can crackle when it is slowly bent. Similarly, small metal or ice crystals deform in a rather jerky way, through a sequence of local slip events that span a broad range of size. In these slip events, weak spots fail in response to the slowly increasing applied shear stress. On a much larger scale, roughly the same phenomenon gives rise to earthquakes, when slow tectonic motion triggers slips of weak spots in the earth's crust. Many other systems exhibit similar failure avalanches, ranging from granular materials to magnets. This project develops a quantitative understanding of the similarities of the avalanche statistics of these systems, many of which were previously studied separately. The goal is to predict to what extent the results and understanding can be transferred from one system to another. Recently, powerful mathematical tools have been developed to answer these questions. These methods will be coupled with computational simulations and comparisons with experiments on plastic deformation of metals, alloys, granular materials, and magnets.

    Results are relevant for a number of applications, including: materials failure predictions and control from nanodevices to bulk materials, nondestructive materials testing, increased materials stability during processing, improved understanding of jamming and avalanches of granular materials, and long-term security of magnetic information storage.

    Education Component: The diverse group of graduate and undergraduate students involved in this project will receive broad interdisciplinary training and will learn to use modern tools from statistical physics, materials science, mechanical engineering, and mathematics. Collaborations with a network of national and international theorists, experimentalists, materials scientists, engineers, and seismologists will be fostered. Simulation codes will be shared with the broader research community.


    Pressure- and Field-Tuned Spectroscopy of Strongly Spin-Lattice-Coupled Materials

    National Science Foundation Award #0856321

    Paul Sokol
    DMR Division of Materials Research
    MPS Directorate for Mathematical & Physical Sciences

    In many oxide-based materials, there is a particularly strong interaction between the atomic magnetic moments (which can be thought of as small bar magnets attached to the atoms) and the ordered "lattice" structure of the atoms; one important consequence of this strong interaction is that applied pressures or magnetic fields can be used to sensitively control the mobility of the electrons in, the magnetic properties of, and even the structural shape of, these materials. As a consequence, these "highly tunable" materials are promising candidates for the next generation of multi-functional switches, sensors, shape-memory structures, and other useful electronic/magnetic devices. This individual investigator award supports a project that will involve the growth of these novel oxide-based materials, and the study of the basic mechanisms responsible for their exotic properties by scattering light (i.e., "photons") from the materials while tuning the materials' properties through their novel phases found at high pressures and high magnetic fields. The goals of this project are to better understand the conditions responsible for the "highly tunable" properties of these materials (i) to elucidate how matter behaves under novel environmental conditions, and (ii) to develop new materials with enhanced functional properties. This project will also provide broad training to 2 graduate students in materials growth and state-of-the-art light scattering methods, and will be used as part of an outreach program to interest K-12 students in the sciences via tours of the high field/high pressure optical laboratory.

    Dates: September 29, 2009–June 30, 2014 (estimated)

    Project NEURON (Novel Education for Understanding Research On Neuroscience) will bring together scientists, science educators, teachers, and students to develop and disseminate curriculum materials that connect frontier science with national and state science standards. The wide-ranging research at the University of Illinois at Urbana-Champaign will allow Project NEURON to link NIH-funded neuroscience research with educational research that examines how teachers and students learn. Project NEURON will also help teachers integrate the newly developed materials into existing state curriculum frameworks. Project NEURON will a) develop and disseminate curriculum modules for use in secondary science classrooms; b) improve instructional practices of secondary science teachers; and c) improve student engagement and learning of key science concepts. In addition to developing curriculum modules, the project will 1) create an ongoing series of professional development opportunities for teachers and graduate students; 2) perform a formative and summative evaluation; and 3) provide a dissemination mechanism for the modules, including presentations at science and science education conferences and article submissions to peer-reviewed journals.

    This is a competing continuation application to renew the Research Training Program in Environmental Toxicology. Established in 2000 to help recruit new scientists into this important discipline, the Program educates pre- and postdoctoral trainees in reproductive, developmental and endocrine toxicology. The need to train students and postdoctoral fellows in these aspects of toxicology is every bit as urgent today as it was 10 years ago when the training program was first conceived. Environmental chemicals that act as endocrine disrupters continue to dominate environmental health concerns. The program unites two long recognized areas of research excellence on the University of Illinois campus, environmental toxicology and reproductive biology, and the investigators can count among their preceptors some of the brightest stars on the University of Illinois campus. Several outstanding new preceptors have joined the Program since the last submission (Flaws, Hofmann) and two additional preceptors are added in this renewal application (Boppart, Freund) resulting in a total of 15 preceptors from seven departments (Animal Sciences, Bioengineering, Chemistry, Crop Sciences, Food Science and Human Nutrition, Molecular and Integrative Physiology and Veterinary Biosciences). Together these faculty currently have over 40 federally funded research grants totaling more than $9 million dollars per year direct costs. The preceptors are researching endocrine active chemicals using a broad multidisciplinary perspective. Collaborations among laboratories working at the molecular, cellular, whole animal and human health levels provide trainees with the unique opportunity to directly observe and participate in translational research. Selection of trainees is based on academic success, relevance of proposed research to Program goals and commitment to toxicology. Preference is given to pre-doctoral trainees in their first or second year of graduate study. The Program offers a broad range of graduate level courses in toxicology. In addition to their departmental requirements, all pre-doctoral trainees take basic toxicology, systems toxicology and at least one other advanced toxicology course related to their field of study. Postdoctoral trainees conduct independent research in toxicology. All trainees are required to attend weekly toxicology research seminars, career development workshops, a toxicology journal club and a course on research ethics in toxicology. Trainees are also required to present their research in the seminar and strongly encouraged to present their research at national meetings. The investigators have a strong record of recruiting and retaining qualified students from underrepresented groups and we will continue and expand these efforts. Relevance: This Training Program will train pre- and postdoctoral students to become the next generation of research scientists in endocrine, developmental and reproductive toxicology, subdisciplines of toxicology that are directly relevant to human health.


    REU Site: Passionate on Parallel—A Summer Research Program for Women in STEM

    National Science Foundation Award #1004311

    Dates: May 1, 2010–April 30, 2014 (estimated)

    The computing landscape is changing—parallel computing will be the "default" approach to programming in the future. A central challenge in the transition to parallelism is shortage of workforce with expertise in parallel programming. In this REU, we will train students in the basics of parallel programming, provide them with research experience that demonstrates its importance in their own fields, and help them develop the confidence that they need to be successful in graduate school.

    To enable undergraduates to participate in the revolutionary new capabilities afforded by parallel computing, the REU-POP program (Research Experience for Undergraduates—Passionate on Parallel) at Illinois will recruit ten (10) junior- and senior-level undergraduates majoring in STEM disciplines to participate in a summer research experience in parallel computing and programming relevant to their own fields of study. Recognizing that women are critically underrepresented in academic and professional computer science, qualified students will be especially sought at women's and minority-serving colleges with limited research or graduate-school options. Eligible students will have completed specified computer science courses, but will not be required to have experience in parallel programming, which is rarely available at the undergraduate level.

    REU students will work in pairs (current literature suggests this is a successful learning strategy for women in programming) in small teams that will include a faculty member in their own discipline and a specially trained graduate mentor. Through preparatory online sessions before the POP summer, a four-day immersion session at the start of the POP summer, hands-on learning in their university laboratory, weekly technical sessions, and special seminars on topics such as parallel computing in current technology; research ethics; technology commercialization; and the benefits of graduate school, students will develop essential skills in parallel programming and explore the research options in their own STEM disciplines. Students will also interact with prominent professional and academic researchers to form a network of diverse role models and mentors to provide advice on careers and graduate school options.

    We believe undergraduates can be encouraged to persist in engineering programs, particularly computer science, by engaging them in research, by employing multiple mentoring options, and by providing opportunities for them to work in "programming pairs." The REU-POP program at Illinois will explore these methods within the REU context, and we will report on their success in the open literature to assist others in this effort.

    This funding renews a highly successful CISE Research Experiences for Undergraduates (REU) site at the University of Illinois at Urbana-Champaign that is focused on parallel computing. The transition to "parallelism as the default" will be a change in the computing landscape of the magnitude of the introduction of the Internet. A central challenge in this transition is a shortage of people with expertise in parallelism. This site will train students in the basics of parallel programming, provide them with application-centric research experiences that demonstrate to them the qualitative impact that parallelism can have on computing applications, and help them develop the confidence that they need to be successful in graduate school. The host institution (UIUC) is well known as a center of parallel computing research and will provide an excellent environment for the REU students to learn about the application of parallelism to a range of scientific and computational problems.

    This site will provide the opportunity for 30 undergraduate students (over three years) to develop essential skills in parallel programming in an application-focused research context and to develop a network of mentors, role models, and peers to inform and advise them about performing research, careers in research, and graduate school. A major motivation for the site is improving the retention of women in the sciences, and the PIs have various strategies for addressing this goal. The PIs will disseminate what they learn about engaging women in computer science research, and will also encourage and facilitate publication by the participating students and their mentors.

    The purpose of this project is to establish an REU site in the area of nanotechnology at the University of Illinois at Urbana-Champaign with support from the NSF Division of Engineering Education and Centers. Students participating in the program will be embedded in a rich environment providing integrated research and educational experiences in a wide range of nanotechnology areas, from nanoelectronics to nanophotonics, nanomaterials and nanobiotechnology. The ultimate goal is to solidify the students' interest in graduate research and education and contribute to the diversity of the national workforce pipeline, through experiences designed not only to expose the participants to cutting edge and interdisciplinary technical aspects of nanotechnology but also to infuse critical thinking, leadership, communication, team-building, and ethics training. Additionally, the assessment and evaluation activities will be embedded throughout the program to determine the effectiveness of the various training components and students will be tracked longitudinally to determine the impact of the program on individuals, institutions and the field as a whole. The REU program will engage ten domestic undergraduate students (rising sophomores to rising seniors) in a ten week summer curriculum on the University of Illinois campus each year, combining a range of common activities (orientations, seminars and workshops) with personalized experiences in the laboratories affiliated with this effort. Students will spend at least 30 hours per week doing research with faculty and graduate student mentors, and will be fully engaged in normal laboratory activities attending group meeting performing literature reviews, running experiments and simulations and keeping laboratory notebooks. Research topics will be assigned matching the interest of the participants and representative projects may include: design of plasmonic nanoparticles for live cell sensing; DNA sequencing through solid state nanopores; design and fabrication of nano-porous conformal films for photonic applications; simulation of charge transport in nanosystems. Capstone of the experience will be participation, during the tenth week of the program, in the campus-wide Illinois Summer Research Symposium where students will present the results of their work.


    Risk-informed Management and Post-disaster Operations of Lifeline Networks by Rapid, Condition-based System Reliability Analysis

    The society is increasingly demanding scientific accountability behind risk management of lifeline networks such as hazard mitigation planning, infrastructure maintenance and post-disaster responses. For rapid and condition-based risk management of lifeline networks, it is essential to have system reliability analysis (SRA) methods that can integrate analyses across physical scales, and can interface models and data from multiple fields of science and engineering smoothly for quantifying system-level risk. The proposed project will develop multi-scale SRA methods employing advanced network clustering algorithms for efficient, accurate and collaborative risk assessment of large-size networks. The project will also create a near-real-time network risk alert system through integration of a rapid SRA method with a hazard alert system to facilitate rapid decision support on hazard responses. In addition, an efficient time-varying network SRA method will be developed in which network reliability is continuously updated based on inspection results of network component deterioration in order to sustain the network reliability with optimal use of limited resources.

    The analysis methods and numerical tools developed in this project will help practitioners understand the hierarchical structure of lifeline networks and its impacts on network risk and decision making, develop network risk alert systems customized for actual risk management practice, and perform condition-based maintenance considering actual deterioration progress and its impacts on network-level risk. Education-focused research tasks include the development of interactive cyber-environment on network theory, virtual experiment on network downtime, interactive computer software simulating network flow and connectivity, and mobile phone applications to demonstrate IT-based risk management. The research results will be incorporated into the graduate level courses on risk and reliability of complex infrastructure systems. Active efforts will be made to recruit students from the groups that are underrepresented in science and technology fields using the well-established institutional fellowship programs.

    This project is using transformational learning theory and an Immunity-to-Change model as justification for forming Communities of Practice (CoPs) to change the teaching culture in gateway STEM courses at the University of Illinois. The Immunity to Change model focuses on the discomfort caused by the many teaching reforms that take the instructor out of the role of routinely providing expertise to the students as the dominant form of interaction with them. When the same instructors are working in or representing their research, it is important to present themselves in ways that demonstrate their expertise. This dissonance is a barrier to changing the teaching practices of research-active faculty in many instances because the teaching practices require them to take on the role of facilitator rather than expert

    Hence, this project is based on the core idea that teaching in gateway courses should be jointly owned and created by the faculty, rather than being the sole province of individual, independent instructors. This process is being initiated through the formation of Communities of Practice (CoPs) around each undergraduate STEM discipline in ten departments, which are located in two colleges - Liberal Arts and Sciences and the College of Engineering. Through the CoP process, the teaching culture is changing, as faculty are adapting evidenced-based reforms and changing their instruction in gateway courses. These gateway courses in ten departments in two colleges enroll over 17,000 students annually, and several of the gateway courses are required for nearly all STEM majors on campus. The Community of Practice approach is operating both within each department and also at the aggregate level across all ten departments. Each CoP is collaboratively exploring a domain of knowledge to support the development of improved practice by connecting faculty who need to adapt their teaching to evidence-based pedagogies with faculty whose beliefs already support those pedagogies.

    CoPs are providing an organizational structure that promotes long-term situated learning that is exposing and challenging instructors' tacit beliefs that impede change. CoPs also depend on high levels of collaboration for success and effectively spread tacit knowledge, which decreases the learning curve for novices, reduces creation of redundant resources or reenactments of failures, and promotes creativity. The emphasis on CoPs will further engender common ownership of the reforms, countering the current individualistic teaching culture, thereby institutionalizing the reforms so that they are used in the gateway courses as new faculty are assigned to teach them.

    CoPs are engaging in a development cycle of innovate to evaluate, facilitated by a large evaluation team and an instructional support team. The evaluation team is providing both formative and summative feedback to CoPs using both qualitative (e.g., student attitudes) and quantitative (e.g., performance outcomes) measures that are in turn being used to improve teaching and learning. In addition, the evaluation team is also studying the functioning of the CoPs, including the extent to which teams are operating as CoPs, and providing detailed descriptions of features of effective and less effective CoPs. The instructional support team is providing just-in-time training to the CoPs by attending their weekly meetings and organizing monthly gatherings for all CoPs. The remaining PIs are working to maintain the top-down administrative support from deans and department heads to sustain the bottom-up reform efforts of the CoPs.

    Dates: October 1, 2010–August 31, 2014 (estimated)

    The goal of this project is to establish a new paradigm of scientific software, electing quantum chemistry as the domain science. The new software does not have a static, compiled code, but instead consists of an expert system and code generator. At every execution, it analyzes the hardware and application parameters, determines (parallel) algorithms, and implements them for one-time use. This strategy not only allows unprecedented flexibility in algorithm optimization but can also realize ideas that are impossible otherwise. Since the approach makes no assumption about hardware or application, it is more extensible, maintainable, and portable. It is particularly well suited for chemistry, where a variety of molecules and reactions is infinite.

    The expected long-term impact of this project is a change in the way scientific and engineering computing software is developed and defined. It promises novel software technology, which simultaneously achieves development efficiency, high product quality, and increased ability to optimize the code and enhance the methodological capabilities, by having no fixed source code.

    Education Component: This project also offers unique, interdisciplinary education for chemistry graduate students, which places exceptionally large focus on computing, the field that has been a driving force of the 21st century economy.

    Micro-chips are at the heart of modern microelectronic systems for computing, communication, entertainment, and other consumer electronics. In order to design and manufacture next generations of complex microelectronic systems, major innovations in the design of EDA (electronic design automation) software are needed. This project addresses four new challenges in EDA for complex microelectronic systems at both the micro-chip and the circuit board levels:

    1. Beyond-die EDA: The routing (wiring) of today’s high-density complex circuit boards has to be done manually since no existing EDA software can solve the problem. Research will be carried out in circuit board routing to handle various new technology issues.
    2. Litho-aware EDA: Since there is no alternative practical option but to continue using 193nm light to print (manufacture) on-chip features of size 32nm and below, accurate printing has become extremely difficult. EDA software will be developed to produce designs that are friendly to lithography for successful micro-chip manufacturing.
    3. GPU EDA: Graphics processing unit (GPU) has become a popular cost-effective parallel computing platform recently. How to take advantage of GPU to accelerate critical EDA tasks is a challenge and will be studied.
    4. Stochastic EDA: In order to handle process variations in advanced technology nodes, EDA software will be designed to solve fundamental graph optimization problems (e.g., shortest path, minimum spanning tree, and network flow etc.) where edge weights (costs) are random variables.

    The proposed research will advance knowledge in EDA. It will also add new knowledge to other fields such as mathematical programming and combinatorial optimization since ultimately the research will need to solve large scale optimization problems.

    Education Component: The broader impacts of this project include technology advancement and the education of next generation of engineers. The proposed research improves the design and manufacturing of microelectronic systems which will benefit the society at large. New research results will be passed on to undergraduate and graduate students through dissertation research, course projects, homework, and classroom teaching.


    Student Use of Digital Learning Materials: Implications for the NSDL

    Dates: September 15, 2010–June 30, 2014 (estimated)

    This large-scale national project is investigating how undergraduate students in STEM disciplines use digital learning materials. Much of the work already done by the National STEM Digital Library (NSDL)—especially by the NSDL large "Pathways" collections)—assumes that students will be directly connected to the content in the collections, or that they will otherwise find and use the digital resources from collections in ways that assist the depth of their learning. However, little is known about how undergraduates use digital resources. This study will develop a better understanding of the extent and nature of undergraduate use and it will begin to determine the value of digital learning materials to undergraduates. The project is:

    1. Examining how undergraduates use digital and distributed learning resources and collections
    2. Documenting how and why they use these resources
    3. Examining the impact of that use on their learning
    4. Exploring student perceptions of barriers to the use of NSDL services and programs

    Following these information collection tasks, the project will begin a second stage to:

    1. Identify possible strategies for overcoming barriers to use of digital libraries and distributed learning resources by undergraduate STEM students
    2. Disseminate the tools developed in this study for use by NSDL projects in developing individual benchmarks regarding their own usage, and
    3. Establish baseline data for future studies of NSDL usage and impact

    This a renewal award to the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign (UIUC) to operate Blue Waters, which is a leadership class compute, network, and storage system, that will deliver unprecedented large scale and highly usable computing capabilities to the national research community. Blue Waters provides the capability for researchers to tackle much larger and more complex research challenges across a wide spectrum of domain than can be done now, and opens up entirely new possibilities and frontiers in science and engineering. This system is located at the newly constructed National Petascale Computing Facility at UIUC.

    This award enables investigators across the country to conduct innovative research in a number of areas including: using three-dimensional, compressible, finite difference, magneto hydrodynamic (MHD) codes to understand how internal solar magneto convection powers the Sun's activity, and how that activity heats the chromosphere and corona and accelerates charged particles to relativistic energies; applying adaptive mesh refinement (AMR) technologies to study flows of partially ionized plasma in the outer heliosphere; implementing multiscale methods to study protein induced membrane remodeling key steps of the HIV viral replication cycle and clathrin coated pit formation in endocytosis; testing of the hypothesis that transport fluxes and other effects associated with cloud processes and ocean mesoscale eddy mixing are significantly different from the theoretically derived averages embodied in the parameterizations used in current-generation climate models; and, exploring systems-of-systems engineering design challenges to discover optimal many-objective satellite constellation design tradeoffs that include Earth science applications. Large allocations of resources on the new system have been awarded to scientists and engineers by NSF through a separate peer-reviewed competition. .

    The Blue Waters system and project are aligned with NSF's Advanced Computing Infrastructure Strategy to promote next generation computational and data intensive applications.

    Surface and Interface Free Energies of Epitaxial Nanocrystals

    National Science Foundation Award #1006077

    Dates: July 1, 2010–June 30, 2014 (estimated)

    Substantial parts of materials technology, major components of chemical industry, and exciting new developments in medical diagnostics and treatments rely on the properties of supported metallic nanoparticles. The unusual functions of metallic nanoparticles come from the synergistic interactions of surfaces and interfaces of nanoparticles and their support. However, modern studies have largely avoided the complexity of supported nanoparticles; nanoparticles are too small for experimental characterization and too big for rigorous theoretical investigations. This project is to study nanocrystal surfaces and interfaces by taking advantage of the recent progress in atomic resolution imaging using aberration-correction in transmission electron microscopy and combining it with nanocrystal synthesis and theory. The research will be integrated with outreach efforts, including high school visits and undergraduate education. Results from this research project will be incorporated in the web-based educational materials for teaching students about atomic structure and diffraction, infrastructure for which is already in place (see http://emaps.mrl.illinois.edu/ or google webemaps). This particular website is now listed as one of the best web resources for learning electron diffraction and electron diffraction pattern indexing in the standard transmission electron microscopy workplace.

    Dates: September 1, 2010–August 31, 2014 (estimated)

    The research objective of this award is to develop mechanically hard and wear-resistant tribological coatings such that: (a) the coating process affords high conformality (i.e., uniform thickness everywhere within reentrant shapes); (b) the coating provides low friction, and low wear under normal operating conditions; and (c) the tribological performance is stable and predictable under extreme operating conditions, such as high load and high temperature. Specifically, low-temperature chemical vapor deposition is used to deposit coatings of the transition metal diborides HfB2, CrB2, and TiB2 using single-source, impurity-free precursors such as Hf(BH4)4. Alloying with nitrogen affords HfBxNy coatings that have a variable elastic compliance; alloying with Cr is used to enhance oxidation resistance; and multilayer coatings are synthesized to engineer the relationship between hardness and elastic response, which affects the tribological behavior.

    If successful, the results of this research will have a significant impact: it will enable the development of advanced devices that are free of lubricants and which have excellent lifetime under aggressive operating conditions. These include, but are not limited to, energy-efficient and oil-free compressors and microelectromechanical-based sensing and actuating devices. Graduate and undergraduate engineering students benefit through involvement in the research. Students spend summer time at Sandia National Laboratories, as well as have direct interaction with both Sandia and Emerson Climate Technologies. The results are broadly disseminated by presentations at domestic and international professional conferences, by publication in upper-tier peer-reviewed scientific journals, by seminars given at university and industrial laboratories, and by news stories that discuss the work as well as the critical role of the National Science Foundation.


    The Applied Baccalaureate Degree: An Emerging Pathway to Technician Education

    National Science Foundation Award #1003297

    Education
    Expires: July 31, 2014 (Estimated)

    The multi-method multi-site targeted research project examines the Applied Baccalaureate (AB) degree within the context of technician education as supported by the Advanced Technological Education Program. The AB degree is a new phenomenon in post-secondary education that allows courses from a terminal applied associate-level degree to transfer directly into a baccalaureate-level degree in STEM. The AB degree provides another avenue to strengthen the accessibility and availability of post secondary education in advanced technology and to meet the growing need for a robust advanced technological workforce in STEM.

    Intellectual Merit: This study is designed to bridge the gap between theory and practice in technician education by the inclusion of the Advanced Technological Education program community in fine turning the research design (to include questions, analyses, and focus on utilization) and in conducting the research. To increase the utilization of project findings, selected PIs of ATE centers and projects are members of the research team. The set of research questions is sufficiently broad to provide a national picture of AB degree programs and targeted to provide a nuanced picture of AB degree programs and efforts in the context of ATE-funded centers and projects. The three-phase study design provides a wide bandwidth complemented by in-depth rich descriptions of individual sites. The project draws on previous work on the AB degree by the principal investigator and a broad network of interested parties that include community colleges and ATE centers and project.

    Broader Impact: Of particular relevance to technician education is the extent to which AB degree programs enroll populations historically underserved by STEM. The resulting findings have the potential to contribute to the research literature on technician education, the viability of AB degree programs in post-secondary education in STEM, the contributions of community colleges in the development of a robust technician workforce in STEM associated with these types of degree programs, and the opportunities and challenges facing the development of AB degree programs that interface with technician education.


    The Smallest Bit: Ultimate Limits of Phase Change in Nanometer-Scale Memory Devices

    Expires: July 31, 2014 (Estimated)

    The objective of this research is to investigate the ultimate scaling of phase change memory de-vices, below 10 nm bit size. Phase-change materials (PCM) undergo a reversible phase change accompanied by a drastic change in resistivity, induced by electric and temperature fields. PCM are prime candidates for fast, high-density memory with ultra-low power consumption. Such a technology would enable scaling of memory devices much beyond the present state of the art, represented by Flash memory or other charge storage devices like DRAM or SRAM. The ap-proach is to investigate the fundamentals of nanometer-scale electric and temperature fields that induce phase change, resulting in an understanding of the smallest data bits that can be formed in PCM. Specifically, the proposed work will perform experiments and simulations that determine the smallest addressable PCM bit using scanning probe techniques and carbon nanotubes as the electrodes.

    The intellectual merit of the proposed research lies in its thorough approach for achieving inde-pendent control of nanometer-scale electric fields and temperature distributions in PCM. In turn, these will allow a significant advance in understanding the behavior of materials used in phase change memory.

    The research will achieve broad impact by providing information about the ultimate speed, size, and longevity limits of future data storage systems. This new understanding could bring about radical changes in consumer electronics devices. The research will achieve additional broad im-pact through web-enabled communication, and personal interactions with high school teachers, undergraduate students, graduate researchers, and U.S. industry.

    William Trent
    Education Policy, Organization, and Leadership

    Dates: August 1, 2009–July 31, 2014 (estimated)

    This is a three-year study that is examining the matriculation, persistence, and degree attainment of full-time, first-time enrolled women, minorities, and low-income undergraduate students in STEM (science, technology, engineering, and mathematics) fields at a consortium of 11 large research universities. This project is using statistical and qualitative research methods to identify key individual and institutional factors that affect underrepresented students' matriculation, persistence, and degree completion in the STEM fields. It is evaluating the impact of course offerings, policies and practices, and program interventions designed to increase educational outcomes. This study is contributing to understanding by using large samples of underrepresented students and placing them into meaningful categories (by racial/ethnic sub-group, academic preparation, and STEM major), as well as the intersection with critical demographic characteristics, such as socioeconomic status.

    The findings from the study are intended to increase understanding about how postsecondary institutions can use mechanisms and program interventions to improve the persistence and degree attainment of underrepresented students in the STEM fields. The study will benefit the academic community by creating a graduate-level course to be offered to students enrolled at any CIC institution to discuss the empirical, methodological, policy, and program issues that impact the representation of women and minorities in the STEM fields, with specific attention to students attending large, research universities.


    Understanding and Enhancing Post-Combustion Multi-Pollutant Control with Carbon-Based Materials

    National Science Foundation Award #1034470
    Mark Rood
    Civil and Environmental Engineering

    Dates: August 15, 2012–July 31, 2014 (estimated)

    The research, educational, and outreach components of this project will allow for the development of unique carbon materials that allow for reduction in emissions of several high and low concentration gas phase pollutants with continuous dissemination of results to all levels of education. NOx, mercury (Hgo/Hg2+), and dioxins/furans (PCDD/F) are emitted from a wide range of sources, including emissions from coal-fired power plants. NOx contributes to acid rain and secondary aerosol formation resulting in ozone, which causes health effects and visibility degradation. Mercury leads to enriched concentrations and heightened toxicity in lake sediments, animals, and humans, while PCDD/Fs are known to be excessively toxic and carcinogenic. Stricter air quality regulations strive to protect human health and welfare. This research will develop new technologies to enhance our ability to consume less toxic materials, prevent the emission of these pollutants to the environment, and provide for a more sustainable existence.

    The intellectual merit of achieving multi-pollutant control involves an international research team at Illinois, URS, Inc., and National Central University, Taiwan, uniquely qualified to study the ability of custom and commercially available carbons to achieve multi-pollutant transformations and removal of toxic air pollutants from flue gas streams. Results will be interpreted and disseminated through national/international collaborations and conferences, educational programs at Illinois, peer-reviewed literature, and K-12 educational programs.

    Broader impacts of this research will effectively integrate research results with K-12 and college undergraduate/graduate education. The key K-12 component is to make students aware of and more interested in engineering solutions to solve environmental issues. Results will be disseminated not only through conventional research conferences and manuscripts, but also via classroom demonstration modules, web-based modules, and in collaboration with The STEM Education Coalition, supported by the Illinois Board of Higher Education. Underrepresented research assistants at the undergraduate level will be recruited through NSF’s supplemental REU Program, and collaboration is planned with college students abroad.

    Dates: September 1, 2011–August 31, 2016 (estimated)

    Vertically Integrated Training With Genomics (VInTG) will provide support for as many as 30 graduate students over the next five years. Students will learn ways to both ask and answer the big research questions of the coming decades, says principal investigator Andrew Suarez, associate professor of Animal Biology and Entomology and IGB affiliate.

    VInTG will address two "grand challenges" in biology: How do genomes interact with the environment to produce biological diversity? and How are biological systems integrated from molecules to ecosystems? Answering these questions will help both science and society determine how to maintain food security under climate change; how to integrate genetics and ecology to study emerging infectious diseases; and how organisms' responses to climate change influence biodiversity and ecosystem function.
