Wei FAN

Welcome! I’m a first-year MPhil student supervised by Prof.Yangqiu Song in Computer Science and Engineering at the Hong Kong University of Science and Technology (HKUST). Before that, I got my B.Eng. degree in Computer Science from Huazhong University of Science and Technology (HUST) and M.Sc. degree in Big Data Technology from HKUST. Please feel free to contact me if you would like to discuss my research further.

Research Interest

My primary research focus lies in large language models and large-scale knowledge graphs. Additionally, I have a keen interest in the fields of privacy and recommender systems.
