I am currently a second-year Ph.D. student at the Institute of Data Science in The University of Hong Kong, under the guidance of Prof. Chao Huang and Prof. Kao, Benjamin C.M.. My research focuses on graph neural networks, large language models, and information retrieval.
Prior to this, I conducted research on data mining at the IIP Lab, advised by Prof. Zhenzhong Chen. I received my B.Eng. degree from Wuhan University. Additionally, I collaborate closely with Dr. Lixin Su from the Baidu Search Science Team.
