Hi! I am a graduate student at the University of Toronto. I'm fortunate to be advised by Toniann Pitassi. Previously, I obtained a M.Sc. from the University of Toronto, and a B.Sc. from School of Mathematical Sciences, Peking University, P.R.China.

(I am currently on leave at Facebook, Inc.)

Research Interest

I am interested in the theory of computation in general. More specifically, my research is focused on approximation algorithms and the hardness of approximation. My other interests include communication complexity, privacy and machine learning.
