I am currently a first-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:
- Reinforcement Learning: applications in graph representation learning, Retrieval-Augmented Generation (RAG);
- Graph Neural Networks: graph prompt tuning, graph active learning, graph self-supervised learning;
- Large Language Models: applications in graph RAG, toxicity detection.
★★★ Feel free to reach out to me for academic discussions and collaborations!
