    UVA Engineering Ph.D. Alumni Elevated to Fellow Status

    January 15, 2021

    Two UVA Engineering computer science Ph.D. alumni have been elevated fellow status. Chenyang Lu, Fullgraf Professor in the Department of Computer Science and Engineering and director of the Cyber-Physical Systems Laboratory at Washington University in St. Louis, has been elevated to ACM Fellow. Lu was recognized for contributions to adaptive real-time systems, real-time virtualization, and wireless cyber-physical systems. He received his Ph.D. from UVA Engineering in 2001 and was advised by John A. Stankovic, BP America Professor of Computer Science and director of the Link Lab.

    Bronis de Supinski, chief technology officer at Lawrence Livermore National Laboratory, has been elevated to IEEE Fellow, and he was recognized for leadership in the design and use of large-scale computing systems. He received his Ph.D. from UVA Engineering in 1998 and was advised by Paul F. Reynolds, professor emeritus of computer science.


    IEEE Intelligent Transportation Systems Society Recognizes ESE Professor’s Research

    January 13, 2021

    B. Brian Park, a professor in the Department of Engineering Systems and Environment, has received the 2014 George N. Saridis Best Transactions Paper Award for Outstanding Research for a paper in IEEE Transactions on Intelligent Transportation Systems. Park co-authored the work with former Ph.D. student Joyoung Lee, now an associate professor of civil and environmental engineering at the New Jersey Institute of Technology. Awards for years 2014-2017 were announced in the journal’s December 2020 issue.

    Park and Lee’s paper, “Development and evaluation of a cooperative vehicle intersection control algorithm under the connected vehicles environment,” was published in the IEEE Transactions on Intelligent Transportation Systems, vol. 13, no. 1, pp. 81–90, Mar. 2012.

    In 2015, the Board of Governors of IEEE Intelligent Transportation Systems Society approved a proposal to name the Best Paper Award in IEEE Transactions on Intelligent Transportation Systems as the George N. Saridis Best Transactions Paper Award. According to the announcement, 2014-2017 winners were named “after nearly five years of preparation and planning, and almost one year of hard and concentrated effort by the Award Committee.”

    IEEE Transactions on Intelligent Transportation Systems is a journal of the Institute of Electrical and Electronics Engineers and a premier publication for basic and applied research to expand knowledge on transportation. It focuses on the design, analysis and control of information technology as it is applied to transportation systems.

    Park also is an affiliated faculty member of UVA Engineering’s Link Lab, an interdisciplinary center for cyber-physical research, and director of the Traffic Operations Laboratory.



    Benton H. Calhoun Elected IEEE Fellow for Pioneering Design of Ultra-low-power Circuits

    December 03, 2020

    The Institute of Electrical and Electronics Engineers has elected Benton H. Calhoun as a fellow for original and fundamental contributions in integrated circuit design. Calhoun, professor of electrical and computer engineering at the University of Virginia, specializes in energy-efficient, sub-threshold circuit design and applications that enable self-powered wireless sensing systems. These wireless sensing nodes are so low power that they no longer need to use batteries. Instead, they operate on power harvested from their environment.


    Esen Yel Recognized for Excellence In Autonomous Systems Research

    December 01, 2020

    Esen Yel, a systems engineering Ph.D. student at UVA Engineering, will give the prestigious Link Lab Student Seminar in recognition of her work to advance drones and self-driving vehicles, or autonomous systems. The seminar is the preeminent talk given by a student in the 280+ person lab; being chosen as the presenter is also a hallmark Link Lab award in recognition of excellence in research.

    Fish and birds use complex high-speed maneuvers when chasing prey or escaping predators. How water and air flow around these animals during maneuvers is mostly unknown. Mapping out these flows will help biologists better understand the relationship between fish, birds, and their environment. Mapping out these flows will help bio-inspired roboticists, who currently rely on models of low-speed, symmetric gaits when designing and testing robots. Understanding the flows that govern rapid maneuvers will enable a new generation of fast, flexible, ultra-maneuverable bio-inspired robots. The principal goal of this project is therefore to discover the fluid dynamics that govern high-speed, asymmetric swimming/flying gaits. The project integrates educational activities, including virtual tours where students from rural high schools teleconference into the lab and remotely control a robotic swimming rig.

    This project is made possible by a unique rig that creates high-frequency, asymmetric flapping motions in a water channel. The rig uses a scotch-yoke mechanism to double the frequencies traditionally available to studies of swimming and flying, and it floats on air bushings in order to simulate autonomous maneuvers. The performance of fish- and bird-inspired propulsion strategies are then quantified by a combination of Particle Image Velocimetry and dynamic force measurements. These experiments will inform adaptations to models of unsteady aerodynamics as they pertain to swimming and flying animals and robots. The experimental-theoretical campaign will focus on three specific research goals: (i) Determine what three-dimensional flow features govern the thrust and efficiency of high-frequency bio-inspired gaits, (ii) Determine what three-dimensional flow features govern the maneuverability of asymmetric bio-inspired gaits, and (iii) Determine what wake-driven models predict the performance of high-frequency, asymmetric, tunable-stiffness fins and wings. More generally, the project?s overarching goal is for the unique semiautonomous rig and the associated modeling to create new precedents and templates for those integrating fluid dynamics into the next generation of intelligent machines.


    Homa Alemzadeh and Research Team Present CognitiveEMS Research at NIST Annual Meeting

    November 12, 2020

    Homa Alemzadeh and her research team have come a long way since winning a $1.1 million grant in 2018 to build an artificial intelligence assistant to help first responders make good decisions during emergency situations. As first reported in 2018, the project’s goal is to develop a wearable, voice-activated assistant that collects sound data from the incident scene and, in response, provides dynamic feedback that would help the responder by suggesting appropriate medical interventions.
