I am currently a Ph.D. student at the City University of Hong Kong, supervised by Prof.Xiangyu Zhao in AML Lab. Before that, I received M.S. and B.Eng degrees from Xi’an Jiaotong University in 2022 and 2019.

My recent research interests include: 1) LLMs for Information Retrieval; 2) LLMs for Recommender System;
