    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


    IEEE Elects Mool C. Gupta as Fellow for Research in Laser-Material Interactions 

    June 13, 2020

    Mool C. Gupta, Langley Distinguished Professor in electrical and computer engineering, has engaged in this research for more than 35 years, the last 16 at UVA where he serves as founding director of the National Science Foundation Industry-University Cooperative Research Center for Lasers and Plasmas. His contributions to laser-material interactions enhance the performance of solar cells, wind turbines and photonic devices and support lunar missions. READ MORE.


    Kyusang Lee Earns NSF CAREER Award for Hemispherical Image Sensor

    June 13, 2020

    Kyusang Lee, assistant professor of electrical and computer engineering and materials science and engineering, built the equivalent of a human eye and its visual cortex to be used as optical sensors for autonomous vehicles, robotics, manufacturing processes or surveillance systems. Lee's device promises to be 1,000 times more efficient in computing than current technology.  READ MORE.


    Necessity = Invention

    June 13, 2020

    Keith Williams, associate professor of electrical and computer engineering, has been working remotely to prototype masks that could be fitted with disposable filters. His design blends plastic and metal 3-D printing with vacuum forming and other techniques. READ MORE.
