I am a fourth-year PhD student at the Gaoling School of Artificial Intelligence, Renmin University of China, under the supervision of Prof. Xu Chen. I hold a bachelor’s degree in Software Engineering from Beijing Jiaotong University. My research interests lie in recommendation systems and LLM-based Agents, with a particular focus on the role-playing, simulation and human-like behaviors of Agents.
