Wentai Liu, Ph.D.

A Short Biography:

Wentai Liu received a B.S. degree from National Chiao-Tung University in Taiwan, a M.S. degree from National Taiwan University, and a Ph.D. from the University of Michigan. He joined North Carolina State University in 1983, where he held the Alcoa Chair Professorship in electrical and computer engineering and was the founder of the Analog/Mixed-Mode Design Consortium. In 2003-2011, he was a professor in the electrical engineering at the University of California, Santa Cruz, where he was the campus director of the NSF Engineering Research Center on Biomimetic Microelectronic Systems. He has been a Distinguished Professor at the Bioengineering Department, UCLA since 2012. His research interests include neuro-engineering, bioelectronics, invasive and non-invasive neural prosthesis, bio- signal processing, brain-machine interface, wireless/wired transceiver, sensors/actuators, timing/clock optimization, computer vision and image processing.

Since its initial stage in 1983, he has leaded the engineering efforts of the retinal prosthesis to restore vision. The venture finally leaded to successful commercial implants for blind patients. He has published more than 250 technical papers and is an inventor of wave pipelining theory and a co-author of Wave Pipelining: Theory and CMOS Implementation (Kluwer Academic). He received 2009 R&D-100 Editor Choice Award, 2010 Popular Mechanics Breakthrough Invention Award, Outstanding Paper Awards from IEEE-CVPR (1986) and ACCV (2009) Conferences, Alcoa Foundation’s Distinguished Engineering Research Award, NASA Group Achievement Award, and the Outstanding Alumni Award from National Chiao-Tung University, where he holds a chair professorship.

He served as guest editors for IEEE proceeding and IEEE Trans. on MTT and is currently an Associate Editor for both IEEE Trans. on Biomedical Engineering and IEEE Trans. on Bio-Circuits and Systems. He is the founder of the International Conference on Neuroprosthetic Devices (ICNPD). He is a technical subcommittee member for the Int’l Solid-State Circuits Conference.
