I am an undergraduate student in Cyberspace Security (Experimental Class) at Beijing University of Posts and Telecommunications (BUPT), with research interests in AI Agents, Trustworthy AI and System Architecture. Previously, I conducted research under Prof. Jie Hao at the National Engineering Research Center of Disaster Backup and Recovery. Currently, I am working with Prof. Jun Liu, focusing on AI Agents Applications and Multi-Agents Protocol.
