Biography

I am a Master's student in Computer Technology at Sun Yat-sen University, advised by Prof. Hejun Wu. I received my B.Eng. in Computer Science and Technology from Central South University in 2025.

Research Interests

My research focuses on how agents collaborate with unfamiliar teammates and people. I study ad hoc teamwork, multi-agent learning, and interpretable policies that turn language-model reasoning into efficient decisions.
