I am currently a PhD student at College of Computer Science and Artificial Intelligence, Fudan University, under the supervision of Prof Yixin Cao. Before that, I obtained my M.S degree at Institute of Automation, Chinese Academy of Sciences, where I was advised by Prof. Yubo Chen and Prof. Jun Zhao. My research interests lie in natural language processing, with a focus on developing agentic large language models.
