About me

Hi there! I am a first-year Ph.D. student at Shanghai Jiao Tong University (SJTU) and Shanghai Artificial Intelligence Laboratory, supervised by Prof. Zhouhan Lin and Prof. Bowen Zhou. I received my B.Eng. from Beijing University of Posts and Telecommunications (BUPT) in 2025 with GPA 3.86/4.00 (Rank: 2/329).

I was previously a research assistant at the Knowledge Engineering Group at Tsinghua University, supervised by Prof. Juanzi Li. I was also a visiting student at Westlake University, supervised by Prof. Yue Zhang. I work closely with Dr. Ning Ding, Dr. Ganqu Cui and Bingning Wang.

Currently, my interest lies in Alignment, Reinforcement Learning, and Pre-Training. If you are interested in these topics, feel free to reach out to me!
