OOI Wei Tsang
Associate ProfessorCo-director, Image & Pervasive Access Lab (IPAL)
- Ph.D. (Computer Science, Cornell University, 2001)
- B.Sc. (Computer & Information Sciences, National University of Singapore, 1996)
Wei Tsang received his B.Sc. (Hon.) degree in 1996 from the Department of Information Systems and Computer Science at NUS (now NUS Computing), and his Ph.D. in Computer Science from Cornell University, Ithaca, New York, in 2001. He spent a year as a postdoc fellow at Berkeley Multimedia Research Center in U.C. Berkeley after the completion of his Ph.D., before returning to join NUS Computing as a faculty member. Wei Tsang's research spans two broad areas: interactive multimedia systems and interactive intelligent systems. His current work focuses on (i) efficient volumetric data streaming via compact, layered 3D Gaussian Splatting (3DGS) representations, and (ii) human-AI collaboration, including learning-to-defer frameworks, vision-language models for driving, and human-drone interaction.
