Background. Zhengpin Li is a Postdoctoral Fellow at the Center of Machine Learning Research, Peking University, co-supervised by Wentao Zhang and Weinan E. He obtained his Ph.D. in Statistics from the School of Data Science, Fudan University in 2025, co-supervised by Yanxi Hou and Jian Wang. He received his B.Sc. in Mathematics from the School of Mathematics, Shandong University in 2019. He worked with Rex (Zhitao) Ying as a visiting student at the Department of Computer Science, Yale University in 2024.

Research Interests. Zhengpin’s research is primarily focused on graph mining, trustworthy machine learning, large language model, and extreme value theory. He has published several papers in top venues such as ICML, WebConf, and Neural Networks. Most recently, he is interested in the following topics,

  • LLM reasoning based on knowledge graphs
  • data-centric LLM pre- and post-training
  • graph foundation models
