I am a second-year Ph.D. student in Artificial Intelligence at The Hong Kong University of Science and Technology (Guangzhou), advised by Prof. Hao Liu. Before that, I received my M.Sc. in Computer Technology from Tianjin University, where I was advised by Prof. Minglai Shao. I also obtained my B.E. in Electronic Information Science and Technology from Dalian Maritime University. My research interests lie in large language models, AI agents, urban computing, and intelligent transportation, with a particular focus on LLM-based reasoning and decision-making in complex urban systems.
