Research Groups

ECE is on the front lines, deeply involved in the explosion of knowledge that is energizing electrical and computer engineering. Our research program has made important contributions in such areas as dependable, resilient and reconfigurable computing, cyber-physical and embedded computer systems, wireless communications, adaptive and nonlinear control, image and signal processing, robotics, photonics, energy and power management, safety assessment and fault-tolerant design, ultra-high-frequency semiconductor and superconducting devices and systems, and in many other emerging technologies.

One reason for the vitality of our programs is our size. With over thirty academic and research faculty, the department is large enough to build areas of substantial strength, while small and flexible enough to respond rapidly to changes in our field. These qualities not only distinguish our research program but also make the department an ideal setting to study electrical and computer engineering. Our students have the opportunity to learn from and work closely with eminent researchers who are actively redefining the state of knowledge in their field.

  • Adaptive Systems and Control Group

    Professor Gang Tao

    Our research is focused on designing resilient control systems capable of maintaining desired performance in the presence of uncertain system faults such as actuator failures, structural damage and sensor failures. We are developing adaptive control techniques for compensation of uncertain actuator failures and nonlinearities, sensor uncertainties and failures, and uncertain structural damage in dynamic systems, for guaranteed feedback control system performance, and apply them to aircraft systems and robotic systems, for resilient and autonomous control.

  • Bean Lab

    Professor John C. Bean

    I teach about microtechnology, nanoscience, and sustainable energy. These are very exciting subjects which deservedly capture a lot of press and public attention. But they are also exceptionally broad and complex subjects. And while they will certainly change our world, it's not clear that all of those changes will be for the better.

  • CHEETAH: Circuit-switched High-speed End-to-End Transport ArcHitecture

    Professor Malathi Veeraraghavan

    CHEETAH is a comprehensive effort to develop the infrastructure and networking technologies to support a broad class of eScience projects and specifically the Terascale Supernova Initiative (TSI). It is a high-performance, experimental, optical network infrastructure connecting UVa, ORNL, NCSU, CUNY, G. Tech, via a three PoP network. The current network deployment consists of three GbEthernet/SONET Sycamore SN16000 GMPLS control enabled switches. We have developed CHEETAH end-host software, consisting primarily of an RSVP-TE client to enable end users and applications to invoke the setup of dedicated GbEthernet circuits between two computers or clusters connected to the CHEETAH network. We have also created a transport protocol for operation on these dedicated high-speed circuits called Circuit-TCP (CTCP). Finally, we have tested applications such as vsftp, bbcp, Ensight (for remote visualization), web caching (with Squid) on dedicated CHEETAH circuits. A detailed control-plane design document about the CHEETAH network is available here.

  • Superconducting Devices and Materials Research Group

    Professor Arthur Lichtenberger

    The SDMRG was once known as 'SIS' for its cutting edge research in the field of SIS (superconductor/insulator/superconductor) heterodyne mixers. In recent years, research within the SDMRG has expanded to include the investigation of materials, processing technologies and devices for a variety of superconducting circuits. The driving force of this research is the need for ultra-low-noise heterodyne receivers at millimeter and submillimeter wavelengths. Of particular emphasis is the investigation of complex integrated balanced and image rejection superconducting-insulating-superconducting (SIS) mixers open to Development Contracts for established mixers.  The group is also researching both diffusion-cooled hot-electron bolometers (d-HEBs) and phonon-cooled hot-electron bolometers (p-HEBs) for submillimeter applications.

  • Thin-Film Device Lab

    Thin-Film Device Lab

    Professor Kyusang Lee

    Thin film device lab, directed by Prof. Kyusang Lee, is aiming to develop heterogeneous integration of the high performance flexible electronic devices which are fabricated by using the epitaxial lift-off (ELO) or remote epitaxy process. The thin film electronic devices can be applied to various applications, such as image sensors, displays, neuromorphic computing, memory and energy conversion devices, with low-cost, low-weight, mechanical flexibility and durability, and simple device integration. For example, the curved detection geometry of a thin-film image sensor allows it to reduce the number of imaging optics by matching the shape of the photodetector plane with the focal plane of the simple lens system, enabling the image sensor with high image quality, low-weight and cost, small size, and reduced complexity.
