I am a 3rd-year PhD student in MIT EECS, advised by Prof. Suvrit Sra. I got my Master degree in EECS at MIT in 2020. Before MIT, I was an undergraduate student in Tsinghua University, major in Electronic Engineering and minor in Statistics. I was fortunate to be advised by Prof. Yuan Shen.

In Fall 2019, I visited Princeton Univerisity and worked with Prof. Chi Jin. In Summer 2017, I was fortunate to join Stanford UGVR program and advised by Prof. Tsachy Weissman. In Fall 2016, I was an exchange student in University of Wisconsin, Madison and worked with Prof. Dimitris Papailiopoulos.

I'm interested in the theory of Reinforcement Learning (RL), especially sample efficiency, robustness and function approximation.
