I obtained my B.Sc (Hons) in Math from National University of Singapore (NUS) and M.Sc from I2R (formerly Institute of System Science), NUS. I obtained my Ph.d in May 1998 from the Department of Computer Science, New York University. I was a post-doc in DIMACS and NEC Research Institute from July 1999 to July 2000. I was with the Department of Computational Science, NUS in 1998 and 2000. Currently, I am an associate professor in the Department of Computer Science, School of Computing, NUS.

Research interests
