About me

I am an assistant professor in the Computer Science Department at the University of Southern California. Previously I spent one year at Microsoft Research, NYC as a postdoctoral researcher. I obtained my PhD from Princeton University, where I was fortunate enough to be advised by Rob Schapire and also to work closely with Elad Hazan. I received my bachelor degree at Peking University working with Professor Zhen Xiao.

Research interests

My research interest is in developing practical machine learning algorithms with strong theoretical guarantees, with a focus on

  • online learning

  • bandit problems

  • reinforcement learning

  • learning in games

  • fast and scalable optimization methods

See below for some of my representative papers (a full list can be found here or at Google Scholar).
