About me

Hi there! I am a 4th-year undergraduate student at the Beijing University of Posts and Telecommunications (BUPT). I was previously a research assistant at the Knowledge Engineering Group at Tsinghua University, supervised by Prof. Juanzi Li. I was also a visting student at Westlake University, supervised by Prof. Yue Zhang. I work closely with Dr. Ning Ding, Dr. Ganqu Cui and Prof. Bowen Zhou.

I am going to pursue a Ph.D. in School of Artificial Intelligence at Shanghai Jiao Tong University (SJTU) and Shanghai Artificial Intelligence Laboratory in 2025 under the supervision of Prof. Zhouhan Lin and Prof. Bowen Zhou.

Currently, my interest lies in LLM alignment, and reward model. If you are interested in these topics, feel free to reach out to me!
