🌟 About Me

Since March 2025, I have been pursuing my Ph.D. degree in Computer Technology at Harbin Institute of Technology, Shenzhen (HITSZ), supervised by Prof. Kehai Chen. Since September 2025, I have also been conducting research at the Shenzhen Loop Area Institute (SLAI). Prior to this, I received my Master's degree from Tianjin University, under the supervision of Prof. Bo Wang.

My primary research interests center on Natural Language Processing (NLP), Large Language Models (LLMs), Agents, and Role-Playing. I am dedicated to exploring the potential of LLMs in simulating human behaviors and interactions. Specifically, I focus on building Role-Playing Agents with enhanced reasoning capabilities and personalization, while investigating their robustness in complex interactive scenarios. My goal is to evolve agents from mere tools into more human-like interactive partners.

I am always open to academic discussions and collaborations. Please feel free to reach out!
