Dr. Valencia Joyner Koomson joined Tufts University in 2005 as an Assistant Professor in the Department of Electrical and Computer Engineering. She completed the B.S. and M.Eng. degrees in electrical engineering and computer science at the Massachusetts Institute of Technology (MIT) in 1998 and 1999, respectively. She received the Ph.D. degree in electrical engineering from the University of Cambridge, UK in 2003.

Prior to joining Tufts, she held an appointment as a VLSI Research Engineer at the University of Southern California’s Information Sciences Institute (USC/ISI), where she performed research on the design of radiation-hardened analog/mixed signal VLSI systems
in CMOS for military and space applications. Her research interests are in the design of silicon-based mixed-mode VLSI systems (analog, digital, RF, optical), analog signal processing, and optoelectronic system-on-chip modeling and integration for applications in optical wireless communication and biomedical imaging. Dr. Valencia Joyner Koomson is a former Marshall Scholar, Intel Foundation Scholar and National Science Foundation Graduate Research Fellow. She is a member of the IEEE Solid-State Circuits Society, IEEE Photonics Society, and IEEE Women in Engineering – Boston chapter Chair.
