I was born and raised in China where I obtained a B. Comp. (Hons 1st Class) from Shanghai Science and Technology University in 1998 and a Master degree in Computer Science from Shanghai Jiao Tong University in 2001. I was conferred a PhD degree in Computer Science at National University of Singapore (NUS). My advisor at NUS was Prof. Ling Tok Wang. I did my Postdoc research with Prof. Chen Li in the Department of Computer Science, University of California, Irvine. I joined Renmin Univesity of China in June 2008.
