I am a first-year Ph.D. student of TCS Group at the University of Illinois Urbana-Champaign(UIUC). My advisor is Prof. Bhaskar Ray Chaudhury. I am also collaborating with Prof. Kate Donahue, Prof. Jugal Garg, and Prof. Ruta Mehta.

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.

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