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)
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.
|Ali received his B.S in
electrical engineering from Yazd University, Iran in 2005
and a M.Sc. degree in electrical engineering from K.N. Toosi
University of Technology, Iran in 2008. His M.Sc. thesis
research focused on the analysis and design of CMOS low-noise
amplifiers for ultra-wideband applications. His doctoral
research work focuses on the development of LED driver circuit
architectures for future-generation visible "smart lighting"
networks, combining high-speed data communication and
|Chirag received his B.E. in Electronics and
Telecommunication Engineering from University of Pune, India in
2008 and an M.S. degree in Electrical Engineering from The George
Washington University, Washington DC in 2010. He joined Dr. Koomson’s
lab in 2010 and is pursuing a Ph.D. in electrical engineering. His
research focuses on the integration of optical signal processing
devices such as filters in CMOS and the analysis and design of CMOS
low-power circuits for bio-medical imaging and sensing applications.
|Ninrat received his B.S. in Electrical Engineering
from the University of Wisconsin-Madison in 2007 and his M.S. in Computer
Engineering from NC State University in 2010. His prior related research
included experiences at: UW-Madison’s Multiphase Flow Visualization and
Analysis Lab and the Wisconsin Electric Machines and Power Electronics
Consortium Lab. His previous related internship experiences include: IBM’s
pSeries Server Disk Drive Qualification and Integration Lab (2004), Hewlett
Packard’s System VLSI Lab (2006-2009), and Intel Corporation’s Massachusetts
Microprocessor Design Center (2010). He is a member of the National Society
of Black Engineers (NSBE) and the Institute of Electrical and Electronics
Engineers (IEEE). He received an Intel-sponsored GEM Fellowship in 2010
to conduct doctoral research work at Tufts on the design of digitally-assisted
analog circuits for circuit health monitoring.
|Enjin received his B.S. in Electronic Information
Engineering from Nanchang University in 2006 and M.S. in Circuit and
System from Southeast University, Nanjing, China in 2009. His M.S.
thesis focused on the design of ultra-wide range PLL frequency synthesizer
with CMOS technology. He joined Dr. Koomson's Lab in the fall of 2010
to pursue his PhD degree. Now he is focusing on integrated and board
level circuit design for RF and optical wireless applications.
|Chenguang Xi received his B.S. in Microelectronics
from Shanghai Jiaotong University, China in 2010. His B.S. thesis research
focused on moving object detection based on GMM using System Generator.
He joined Prof. Koomson’s lab in 2010 and is pursuing a M.S in electrical
engineering. His research work focuses on development of network interface
circuits "smart" solid-state lighting systems, combining high-speed data
communication and illumination control.
