🎓 About Me

I am a Postdoc with Prof. Jiannong CAO (since 2024) at the Department of Computing, Hong Kong Polytechnic University. I earned my Ph.D. from the same department under the supervision of Prof. Xiao HUANG (2021–2024). Prior to that, I obtained my B.E. from Fudan University.

My research interests include knowledge graphs, Large Language Models, and Retrieval-Augmented Generation (RAG), with latest research presented at Top-tier Venues including NeurIPS, ICML, ICLR, AAAI, TKDE, ACL, CIKM. Currently, I am working on Graph-based RAG.
