Welcome to my personal website! I am a third year Ph.D. student in The Institute for Computational and Mathematical Engineering (ICME), Stanford university, working with Prof. Vasilis Syrgkanis. Prior to joining Stanford, I obtained my bachelor degree in computational mathematics in the School of Mathematical Sciences, Peking University, fortunately having Prof. Liwei Wang as my research advisor. I am broadly interested in any research questions that combine theoretical insights with real-world impact. My recent research interests include (1) understanding fundamental limits of ML-empowered estimation methods and (2) applying statistical tools to enhance LLM evaluation. If you share similar interests, feel free to contact me via email or Wechat. Download my resumé.
