Welcome to my personal academic website

About

I am currently a Ph.D. student at Northwestern Polytechnical University, fortunate to be advised by Prof. Zhen Wang and co-advised by Dr. Qiaosheng Zhang at Shanghai AI Laboratory. Before that, I received my B.S. and M.S. degrees from Beihang University, where I was advised by Prof. Zhiguo Jiang. My research interests include graph learning, machine learning theory, multimodal large language models, and LLM safety.

Selected Projects

Research Experience

Mar. 2025-present

Center for Safe and Trusted AI, Shanghai AI Laboratory

  • Improved LLM safety through co-evolving attacker-defender adversarial games, where attack and defense strategies are iteratively optimized against each other.
  • Worked on unlearning for LLMs with mixture-of-experts architectures, focusing on removing target knowledge or behaviors while preserving the model's general capabilities.
Oct. 2024-Apr. 2025

Collaboration with Shanghai Innovation Institute

  • Developed an agent for Chinese porcelain and antique appraisal, integrating visual understanding, tool use, and domain-specific cultural knowledge.
Apr. 2024-Oct. 2024

Frontier Research Center, Shanghai AI Laboratory

  • Conducted research on the theory of graph neural networks and attention mechanisms.
