About me

I’m Zongqi Wang. I am currently a second-year master’s student supervised by Prof.Yang at Tsinghua University. I received my bachelor’s degree from Xidian University. My previous research focused on AI Safety. Now, my research interests are primarily in Large Language Model, Reinforcement Learning, Reward Model, Character Model, Role-Playing, LLM-as-a-Judge and LLM Evaluation.
