I am a 2nd-year Master's student at the School of Information, Renmin University of China, and a member of the AIM³ Lab. My research interests include multimodal large language model reasoning and evaluation, video understanding, and AI for Sports.

I am fortunate to be advised by Prof. Qin Jin and Assistant Prof. Wenxuan Wang. Before starting my graduate study, I was an undergraduate student in the Turing Experimental Class at RUC, and received my B.Sc. degree in 2024. I am currently a research intern at Meituan, working with Songxiang Liu.

Outside research, I am passionate about sports, especially badminton. I am also exploring fitness and have a strong interest in esports. We are actively exploring topics in video understanding and AI for Sports, and I am always happy to discuss related ideas. Please feel free to reach out if you are interested.
