OOI Wei Tsang

Associate Professor

  • Ph.D. (Computer Science, Cornell University, 2001)
  • B.Sc. (Computer & Information Sciences, National University of Singapore, 1996)

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 volumetric 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.
