I am now a researcher at Tencent Youtu Lab, specializing in the research of Large Language Model-based techniques, e.g., GraphRAG. I obtained my Ph.D. degree from The Hong Kong Polytechnic University, Department of Computing, supervised by Prof. Xiao Huang and Prof. Qing Li. I was nominated by both the Department of Computing and the Faculty of Computer and Mathematical Science of Hong Kong Polytechnic University as the ‘Best Research Postgraduate Student’ of 2024.

My current research interests focus on Large Language Models and Knowledge Graphs, especially in exploring GraphRAG for various domains-specific scenarios.
