About me

I am currently an Assistant Professor in the School of Mathematical Sciences and Center for Machine Learning Research at Peking University.

Previously, I was a postdoc in PACM at Princeton University and in the Wharton Statistics and Data Science Department at the University of Pennsylvania. I completed my Ph.D. in computational mathematics at Peking University in 2018, advised by Prof. Weinan E. I received my B.S. degree in mathematics from Nankai University in 2012.

My current research focuses on understanding the mechanisms behind machine and deep learning, specifically:

  • The approximation and representation power of neural networks

  • The convergence and implicit bias of optimization algorithms like SGD and Adam

  • The emergent phenomena observed in the training of foundation models

Openings

We are actively seeking self-motivated postdocs, PhD students and interns to join our team, particularly those with backgrounds in computer science and physics. If you are interested in collaborating with me, please do not hesitate to reach out via email.
