Hi! I am a third-year PhD student in Computer Science at Princeton University, where I am very fortunate to be advised by Matt Weinberg. I have a broad interest in theoretical computer science, especially algorithmic game theory.

Prior to joining Princeton, I completed my undergrad in Yao Class, Tsinghua University. During my undergrad studies, I was also fortunate to work with Aviad Rubinstein at Stanford, Hu Fu and Zhihao Gavin Tang at SHUFE, and Jian Li at Tsinghua.
