Dr. Joyner 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. Joyner 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.

Graduate Students

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 focuses on the development of low-power biomedical sensor architectures with high sensitivity, spectral and temporal resolution for near-infrared spectroscopy instrumentation.	Ruida Yun Ph.D. candidate
Scott Pruessing received a B.S. in Computer Engineering from Tufts University in 2008. He is currently working in Prof. Joyner’s lab on developing a control system for the Soft-Bodied Chembot project. His work will focus on Shape Memory Alloy control, battery power consumption, and biomimetic neural systems. He is also working on developing gripping systems that will be used in the Soft Body Robot Project. He hopes to pursue graduate work in Computer Engineering and VLSI design.	Scott Pruessing M.S. candidate
Ali Mirvakili 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 optoelectronic VLSI circuit architectures for future-generation visible "smart lighting" networks, combining high-speed data communication and illumination control.	Ali Mirvakili Ph.D. candidate
