Ph.D. Student

Department of Computer Science

I am a third-year PhD student in Computer Science at Yale University, where I am fortunate to be advised by Prof. Yang Cai. I received my bachelor’s degree in EECS at Peking University, where I was fortunate to be advised by Prof. Xiaotie Deng. During my undergraduate study, I also worked closely with Prof. Lirong Xia.

I have a broad interest in theoretical computer science, optimization, machine learning, and economics. Currently I focus on min-max optimization and online learning in games, and try to provide theoretical understanding of deep learning and reinforcement learning.

Interests

Algorithmic Game theory
Online Learning
Min-Max Optimization
