I am a first-year Ph.D. student of TCS Group at the University of Illinois Urbana-Champaign(UIUC). I am fortunate to be guided by Prof. Bhaskar Ray Chaudhury. 

Before that, I received my bachelor’s degree in computer science from Shanghai Jiao Tong University in 2023. I was very fortunate to be guided by Prof. Biaoshuai Tao in the direction of algorithmic game theory. Prof. Qinxiang Cao, Shengxin Liu, and Yuhao Zhang also provided me with great help and guidance. I also had a fantastic experience working as a research intern with Prof. Yu Feng in the summer of 2023 and 2024.

I enjoy writing novels and listening to LPs in my spare time. 

Research Interest: My current research interests focus on algorithmic game theory (check the research page for more).
