I am a first-year PhD student of Multimedia Laboratory at The Chinese University of Hong Kong supervised by Prof. Wanli Ouyang. Before that, I obtained my Bachelor’s degree from the Honor Class of Artificial Intelligence at Shanghai Jiao Tong University. My research interests lie in Large Language Models, Multi-agent Systems, and Reinforcement Learning.
