Welcome to my webpage :-)

I'm a Ph.D candidate at SOC, NUS. My supervisor is Assoc. Prof. Roger Zimmermann.
I'm doing research on optimization for multimedia systems, especially multimedia transmission over networks, using efficient algorithms. My research interests cover (Wired, Wireless and P2P) Networks, (Distributed, Approximation) Algorithms, and Multimedia (Audio, Video).
