I am a PhD student in the Machine Learning Department at Carnegie Mellon University. My advisor is Zachary Lipton.

I finished my Master program in the Department of Computing Science at the University of Alberta working with Csaba Szepesvári and András György in 2016. I received my Bachelor's degree in Computer Science from Shanghai Jiao Tong University in 2013.

From 08/2017 to 11/2017 I interned at Google DeepMind, London.

From 05/2018 to 08/2018 I interned at Google Brain, Mountain View.

From 05/2019 to 08/2019 I interned at Google Brain, Mountain View.

Research

My research focuses on fundamental problems in pushing machine learning into practical use. I am currently working on (i) reinforcement learning, and (ii) understanding the generalization behavior of neural networks.
