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. I also work closely with Dr. Zhuoran Jin. My research aims to build knowledgeable, fully autonomous intelligent agents. Specifically, my work focus on knowledge for agents, enabling agents to continually acquire, maintain, and leverage knowledge through interaction with real-world environments.
