About Me

I’m a fourth-year undergraduate at Fudan University, majoring in Computer Science. I will join the College of AI, Tsinghua University as a PhD student in Fall 2027. My research interests lie in natural language processing, with a focus on developing agentic large language models and embodied agents.
