Current position

I'm an associate professor in Department of Computer Science and Engineering (CSE) at The Chinese University of Hong Kong (CUHK). I'm also a member of  Institute of Theoretical Computer Science and Communications (ITCSC).


I obtained my B.S. in mathematics, Fudan University in 1999 with the highest GPA in the department, and then got my M.S. in computer science, Tsinghua University in 2002, under the supervision of Prof. Mingsheng Ying. I was lucky to be one of the first two students of Prof. Ying in Tsinghua. I obtained my Ph.D. in computer science, Princeton University in 2006, under the supervision of Prof. Andrew Chi-Chih Yao, the Turing Award winner of 2000. It was my great honor to be his last student in the US. After that, I worked in NEC Laboratories America for a summer, before moving to California Institute of Technology for a two-year postdoc in Computer Science Department and Institute for Quantum Information. I had a great pleasure to work with my advisors Prof. Alexei Kitaev, Prof. John Preskill, and Prof. Leonard Schulman.
