I am an associate professor in Department of Computer Science and Technology, Xiamen University. I am also affiliated with Media Analytics & Computing Laboratory (MAC Lab). I received my Ph.D. degree in Computer Science from University of Hong Kong. 

My research interests lie in Information Retrieval, Data Mining and Data Management. My recent projects focus on the following areas:

(1) Recommender Systems (Large Language Model Based Recommendation, Shilling Attack and Defense, Bias Analysis and Debiasing)

(2) Information Retrieval (Generative Information Retrieval, Code Retrieval)

(3) Large Language Model (Retrieval-Augmented Generation, Multi-Modal Large Language Model)
