I am a fourth-year year Ph.D. student majoring in computer science at the Institute for Interdisciplinary Information Sciences in Tsinghua University. I am very fortunate to be advised by Professor Andrew Chi-Chih Yao, who is the A.M. Turing laureate of 2000. I received my B.S. degree in artificial intelligence from Peking University in 2021, advised by Professor Liwei Wang.

My research focuses on machine learning, both on theoretical side and application side. I enjoy establishing theoretical guarantees of generalization and optimization of deep learning algorithms. My current research focuses on designing practical and theoretically-sound optimization algorithms to pretrain and finetune large language models. I have previously worked on topics including generalization, adversarial robustness, federated learning and differential privacy.
