Dr. Valencia M. Joyner joined the Department of Electrical and Computer Engineering at Tufts University as an Assistant Professor in 2005. She completed the B.S. and M.Eng. degrees in electrical engineering and computer science at MIT in 1998 and 1999, respectively. She received a Marshall Scholarship in 1999 to pursue a Ph.D. in electrical engineering at the University of Cambridge, UK. 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). Her research interests are in silicon-based analog/mixed-signal integrated circuits with a particular focus on circuits that interface with photonic devices for high-speed communication, sensing, and biomedical imaging. Dr. Joyner is a former Marshall Scholar, Intel Foundation Scholar and National Science Foundation Graduate Research Fellow.

Graduate Students

Scott Pruessing received a B.S. in Computer Engineering from Tufts University in 2008. He is currently pursuing a MS degree in Computer Engineering at Tufts and his research work involves developing integrated controller hardware for biologically-inspired robots. His work focuses on shape memory alloy (SMA) control, active/passive gripping system, and low-power biomimetic VLSI systems for soft-bodied robot control.	Scott Pruessing M.S. candidate
Ruida Yun received his B.S. in electrical engineering and automation from Zhejiang University, China in 2003 and a M.S. degree from the Royal Institute of Technology (KTH), Sweden in 2006. His M.S. thesis research focused on digital calibration of pipelined ADCs for wireless applications. He joined Prof. Joyner’s lab in 2006 and is pursuing a Ph.D. in electrical engineering. His doctoral research work involves designing a multi-spectral optical sensor for frequency-domain optical tomography systems.	Ruida Yun Ph.D. candidate
Yiling Zhang received his B.E. in electrical engineering from the Harbin Institute of Technology (HIT), China in 2006. At HIT, Yiling completed an undergraduate research project on the design and fabrication of silicon-based micro direct methanol fuel cells (µDMFC). He will complete his M.S. degree in August 2008 on the design and implementation of hybrid-integrated CMOS optical diversity receivers for multi-gigabit free-space optical MIMO systems.	Yiling Zhang M.S. candidate
Juan Zeng completed her B.E. in electronic science and technology at the Harbin Institute of Technology (HIT), China in 2007. She received the Dean’s Fellowship in 2007 to pursue a M.S. in electrical engineering at Tufts University. Her current research focuses on low-noise readout circuits for MEMS sensors and high-performance circuits for broadband wireless applications.	Juan Zeng M.S. candidate
