Profile

Wei Tsang’s received his B. Sc. (Hon.) degree from the Department of Information Systems and Computer Science (now School of Computing), NUS in 1996, and his Ph. D. in Computer Science from Cornell University, Ithaca, NY in 2001. He spent a year as postdoc at Berkeley Multimedia Research Center in U.C. Berkeley after his Ph. D. before returning as a faculty member to NUS. Wei Tsang’s research interests fall under the general area of interactive and networked multimedia applications. His current research focuses on zoomable video streaming, networked virtual environments, and cloud gaming systems. He is also keen in building multimedia systems that contributes towards better wellness and healthcare for all.
