    Joe C. Campbell’s Photodetector Supports Next-Generation Optical Clocks for Navigation, Astronomy and Physics Experiments

    June 23, 2020

    Joe C. Campbell, Lucien Carr III Professor of electrical and computer engineering, developed the photodiode for a research effort led by NIST with the University of Colorado-Boulder. The team discovered how to convert high-performance signals from optical clocks into a microwave signal that can more easily find practical use in modern electronic systems. The opto-electrical converter allows communications systems to maintain stable and accurate microwave signals over long distances. Their research is published in the May 22, 2020 issue of Science.


    UVA Engineering Team Among Eight Finalists in NASA's BIG Challenge

    June 13, 2020

    NASA has selected UVA Engineering to develop and demonstrate a laser technology that will power exploration on the dark side of the Moon, one of eight universities awarded  funding through NASA's Breakthrough, Innovative and Game-changing (BIG) Idea Challenge to benefit the Artemis program. An undergraduate team led by UVA Langley Distinguished Professor Mool C. Gupta will build a prototype called Beaming of Sun Light Energy via Laser for Lunar Exploration. BELLE will make it possible to energize systems operating in the darkness without those systems having to leave the crater or carry their own power sources.  READ MORE.


    Hutchinson Applies Electrical Engineering Skills to Make Robotic Surgery More Intuitive

    June 13, 2020

    Ph.D. student Kay Hutchinson has designed an autonomous closed-loop camera arm system for robotic surgery. The robotic arm can detect and autonomously respond to objects in the surgical field. Hutchinson and her advisor Homa Alemzadeh will present the design at the International Symposium on Medical Robotics in November. READ MORE.


    ACS Journal of Infectious Diseases Publishes Research on Rapid Screening for C. diff Infection

    June 13, 2020

    John Moore, a Ph.D. student of electrical engineering and 2019 UVA Global Infectious Diseases Institute Fellow, collaborated with researchers in electrical and computer engineering, biomedical engineering and UVA’s School of Medicine to stem C. diff infection, the primary cause of antibiotic-associated diarrhea and colitis. Their rapid screening method assesses how well probiotic combinations may restore the gut’s microbiome following an antibiotic regimen. READ MORE.


    Nature and Nature Nanotechnology Publish Papers by Kyusang Lee

    June 13, 2020

    Kyusang Lee has extended his seminal research in epitaxy—the growth of a crystalline material on a substrate—to semiconductors used in electronic and photonic devices. Lee’s process to fabricate free-standing semiconductor film achieves a dramatic improvement in the quality of the material platform and enhances the functional properties and affordability of next-generation devices.

    Nature Communications Publishes UVA and Peking University's Innovation in Microcombs

    June 13, 2020

    Xu Yi, assistant professor of electrical and computer engineering at the University of Virginia, collaborating with Yun-Feng Xiao’s group from Peking University and researchers at Caltech, applied chaos theory to demonstrate the broadest microcomb spectral span ever recorded. The broad spectrum of light generated from the photons increases the device's usefulness in spectroscopy, optical clocks and astronomy calibration to search for exoplanets. READ MORE.


    Research in Asynchronous Computing Earns IEEE Top Paper Awards

    June 13, 2020

    2019 Ph.D. graduate Patricia Gonzalez and her advisor Mircea Stan detailed a signal processing algorithm for asynchronous computing—an approach that mimics neural networks to continually parse and transmit bytes of information—in a paper that earned Gonzalez a top student paper award at IEEE's Latin American Symposium on Circuits and Systems. They then addressed the theoretical foundations of asynchronous computing, earning a best paper award at the November 2019 Asilomar Conference on Signals, Systems and Computers. Asynchronous computing allows sensors to process information while using very low power. READ MORE


    Lichtenberger Earns Terahertz Science and Technology Best Paper Award

    June 13, 2020

    Arthur W. Lichtenberger, research professor in electrical and computer engineering, joined co-authors from the California Institute of Technology and the Universidad de Concepción of Chile to develop a faster and more accurate way to calibrate radio telescope receivers. Their programmable calibration load offers a dramatic improvement over standard calibration methods that are manual and binary. READ MORE
