I am a Ph.D. student of the AGI Lab in the Department of Computer Science at the University of California, Los Angeles, advised by Prof. Quanquan Gu. I received my B.Sc. at the School of Mathematical Sciences at Peking University.

My research focuses on optimization and RL applied to the pre-training and post-training of LLMs. I am also interested in sampling based-methods, including the diffusion models and their applications. I am fascinated with in how the dynamics of high-dimensional models are shaped by the low-dimensional structure of the data and training algorithms.
