Welcome to my homepage! I am a Ph.D. student at HKU CS, advised by Prof. C.M. Kao. I also work with the NLP group of Shanghai AI Lab and HKUNLP, focusing on topics related to LLM Agents. Previously, I was a master’s student at NUS, advised by Dr. Xiaoli Li at the Institute for Infocomm Research (I²R), A*STAR. Before that, I completed my B.Eng with distinction in the School of Data Science and Engineering (DaSE) at East China Normal University, where I was privileged to be instructed by Prof. Weining Qian, Prof. Xuesong Lu, and Prof. Xiang Li for research and engineering projects.

My research interests include neural code intelligence, LLM-based agents, and broad deep learning topics in general.
