About
I am a postdoctoral research scholar in the Decision, Risk, and Operations Division at Columbia Business School, working with Hongseok Namkoong and Assaf Zeevi. I earned my PhD in Management Science and Engineering from Stanford University, where I had the privilege of being advised by Peter Glynn and Jose Blanchet. I completed my bachelor's degree in Mathematics at the University of Science and Technology of China (USTC).
I am on the 2025-2026 job market.

Research
I am interested in studying Markovian systems, including Bayesian bandits.
