I am now a third year Ph.D. student at THUIR, Department of Computer Science and Technology, Tsinghua University. I received my B.S. degree in Computer Science (2022) and my minor degree in Psychology (2023) from Tsinghua University.

My major research interests lie in Recommender System (RS) and Large Language Models (LLM). Currently, I focus on the following topics: Explainable Recommendation, LLM for Personalization and User Modeling.

Please feel free to contact me if you are interested in my research and looking for possible collaborations!
