I am an incoming Ph.D. student of HKUST at KnowComp , supervised by Yangqiu Song. Currently, I am a master student of CUHK supervised by Prof. James Cheng. I also got my B.E. degree from BJTU. I also worked as a Research Assistant in the Center of Machine Learning Research of PKU, supervised by Prof. Wentao Zhang. Before that, I also worked as a Research Intern in the INSIS lab of BJTU, supervised by Prof. Huaiyu Wan.

My research interests include: Data Mining, Large Language Models, Knowledge Graph and Recommendation System.
