I’m a Ph.D. student at CISPA Helmholtz Center for Information Security, where I am fortunate to be advised by Prof. Michael Backes and Dr. Yang Zhang. Prior to coming to CISPA, I received my Bachelor’s degree from Sichuan University, where I daily worked with Prof. Cheng Huang. During my undergraduate, I was also a security engineer intern at Alibaba.

My research focuses on designing and developing trustworthy AI systems, ensuring they are safe, privacy-preserving, and secure. I am also interested in the responsible use of AI, with a focus on transparency and preventing the misuse of AI-generated content. Currently, I am passionate about building generative agents for security and privacy tasks, as well as social behavior simulation.
