About me
Hello! I am an incoming PhD student at USC. Previously I earned my Bachelor’s degree in Computer Science and Technology (IEEE Pilot Class) from Shanghai Jiao Tong University (SJTU). I am also the member of APEX lab, advised by Prof. Weinan Zhang and Prof. Yong Yu. before this, I had a wonderful research experience at Professor Quanshi Zhang’s XAI Lab.
My research interests include machine learning and data mining, especially, recommender system and information retrieval. I am also interested in the interesting applications of LLMs in recommender system.
