Welcome to my personal website! I am an incoming Ph.D. student of the The Institute for Computational and Mathematical Engineering (ICME) at Stanford university. Prior to joining Stanford, I obtained my bachelor degree in computational mathematics at 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, operations research. While primarily 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.

Jan. 2023 Our operator learning paper is accepted by ICLR 2023 as spotlight presentation.
We prove that GD applied to the matrix sensing problem has intriguing properties – with small initialization and early stopping, it follows an incremental/greedy low-rank learning procedure. This form of simplicity bias allows GD to recover the ground-truth, despite over-parameterization and non-convexity.
We consider the problem of learning a linear operator between Sobolev RKHSs from noisy data. Different from its finite-dimensional counterpart where regularized least squares is optimal, we prove that estimators with a certain multilevel structure is necessary (and sufficient) to achieve optimality.
