Strategic Research Initiatives

Research. Collaborate. Innovate.

At Illinois, collaboration is part of our culture and factors into our research success. Indeed, many of the most important innovations of the past century can be tied to new knowledge, discovery, and research advanced by the disciplinary excellence and interdisciplinary nature of our faculty, alumni, and students.

Today, Engineering at Illinois is well positioned and well prepared to respond to the critical needs of society and to develop solutions for our global challenges.

Current Strategic Research Initiatives

To expand research and support collaboration in new and emerging areas, the College of Engineering recently introduced its Strategic Research Initiatives program. SRI supports exploratory research in emerging fields and enhances existing capabilities for new interdisciplinary focus areas or centers. Funding for the SRI programs comes primarily from the College of Engineering.

SRI-BigDataAnalytics

SRI-Detection-of-Nuclear-Materials

Detection of the Illicit Movement of Nuclear Materials with Big Data

Clair J. Sullivan, nuclear, plasma and radiological engineering; Roy H. Campbell, computer science; Shaowen Wang, geography and geographic information science

Detecting terrorist movement of nuclear or radiological materials is of paramount importance to society. Standoff detection of nuclear or radiological materials, shielded or otherwise, is challenging because the signal at large distances is small, the background and noise are large, and signal acquisition times need to be short (thus further hampering the statistics of detection). The project goal is to establish a first-of-its-kind collaboration between radiological engineers, computer scientists, and GIS experts to explore how the fusing of publicly available data with a radiation sensor network to locate radiation sources, either fixed or moving.

SRI-high-throughput

High-Throughput Single-Molecule Biophysics and Biomolecular Sensing

Songbin Gong, electrical and computer engineering; Rohit Bhargava, Sua Myong, and Andrew Smith, bioengineering; Brian Cunningham, bioengineering/electrical and computer engineering

Recent advances in single-molecule imaging, detection, and manipulation have vastly expanded our understanding of biology. Optical tweezers, atomic force microscopy, and single-molecule optical microscopy are providing critical insights into the physical structure, function, and dynamics of proteins and nucleic acids, and revealing mechanisms of molecular dysfunction in disease. However, these techniques are notoriously low-throughput and require specialized, expensive equipment and extensive training. For these reasons, single molecule techniques remain a niche field inaccessible to non-specialists, and limited progress has been made toward commercialization.

A New Paradigm in Ultrasonic Image Formation: Inverse Scattering

Michael L Oelze and Weng Chew, electrical and computer engineering; William Gropp, computer science

Currently more than 3 billion ultrasound exams are performed each year which far exceeds all other imaging modalities except for conventional x-ray imaging. However, while ultrasound has many advantages over other imaging modalities, the quality of conventional ultrasonic images is not competitive with magnetic resonance imaging, and X-ray computer aided tomography. For several decades, ultrasonic image formation has relied upon simple delay and sum beam formation. While such techniques have been highly developed and can provide real-time imaging capabilities, the resulting images are characterized by speckle and are affected by reverberation and aberration. Therefore, in order to improve upon existing ultrasonic imaging techniques a fundamental change in the paradigm of image formation must be adopted. The proposed research will dramatically affect how clinical ultrasound imaging is performed in the future.

SRI-WBG

Wide-Bandgap (WBG) Power Electronics Research Initiative toward a Center of Excellence and Entrepreneurial Opportunities

Kyekyoon (Kevin) Kim, Elyse Rosenbaum, and Philip T. Krein, electrical and computer engineering

Wide bandgap (WBG) semiconductors are recognized for their potential to revolutionize electric power systems, supporting disruptive changes in power electronics. The market for WBG power electronics is growing rapidly. While the initial emphasis has been on SiC, GaN holds the promise of better performance in high-speed and very high voltage applications and is, of course, uniquely suited for optical applications. It is projected that the GaN sector will top $2B within 5 years. With applications as diverse as hybrid cars, photovoltaic inverters, lighting, distributed generation, and communications – at voltages ranging widely from a few volts to tens of thousands of volts – WBG power electronics will take on a leading role over the next decade. This project proactively pursues strategic GaN-based power electronic device research, with a goal to establish a center for excellence and to explore entrepreneurial opportunities and attracting external funding for this growing research sector.

SRI-Atomic-Scale-Design

Atomic-Scale Design of Oxide Heterojunctions for Energy Conversion

To produce dramatically improved photocatalysts for solar hydrogen production as well as energy-efficient environmental remediation, researchers are pursuing a transformative approach for designing and synthesizing oxide heterojunctions for photocatalytic (PC) energy conversion devices. Their unique approach combines semiconductor defect engineering to control the concentration and lifetime of photo-stimulated charge carriers, semiconductor band engineering to control the flow of charge carriers within the photocatalyst, the use of “hot” carriers with greater than thermal energies, and atomic-scale modeling of the free surfaces and solid-solid interfaces to optimize atomic defect profiles during synthesis and carrier flow during operation.

SRI-DNA-Storage

Optimizing DNA Storage Efficiency via Joint Constrained and Error-Control Coding

Olgica Milenkovic, electrical and computer engineering; Jian Ma, bioengineering; Huimin Zhao, chemical and biomolecular engineering

The interdisciplinary team will address a set of problems with potentially far-reaching consequences for the future of DNA storage. The questions of interest include finding the ultimate theoretically achievable limits of DNA-based recording techniques; designing tailor-made joint constrained and error-control coding methods for DNA media that optimally exploit the properties of the system; designing universal coding methods invariant to the technology used for DNA synthesis and sequencing (Illumina versus Roche versus PacBio or some other emerging platform); and how significant will the cost savings ensured by near-optimal coding schemes be? The team will address these challenging questions both from an analytical and an implementation-based point of view—exploring how current design techniques may be improved, while developing new DNA sequence storage paradigms in an experimental setting.
