Welcome to my personal website! I am a first-year Ph.D. student in The Institute for Computational and Mathematical Engineering (ICME), Stanford university. 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. My research is highly interdisciplinary across machine learning, statistics and operations research. While currently focusing on theoretical aspects, the ultimate goal of my research is to develop state-of-the-art solutions for important real-world problems. If you share similar interest, feel free to contact me via email or Wechat. Download my resumé.

Jul. 2023 Graduate from Peking University! Will miss the time spent there.
We investigate the “grokking” phenomenon in deep learning on some simple setups, and show that it is caused by a dichotomy of the implicit biases between the early phase and late phase during training.
