I am currently a first-year post-graduate Student at the School of Data Science and Engineering, East China Normal University, under the supervision of Prof. Xiang Li in the PLANING (graPh mining and LANguage processING) lab.

My research interests include:

• Large Language Models: applications in GraphRAG, toxicity detection, and detoxification.
• Reinforcement Learning: applications in LLM reasoning.

★★★ Feel free to reach out to me for academic discussions and collaborations!
