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

My research interests include:

• Agentic Reinforcement Learning: algorithms and applications in agentic tool use, skill augmentation.
• Large Language Models: applications in graph RAG, toxicity detection.
• Graph Neural Networks: graph prompt tuning, graph active learning, graph self-supervised learning.

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