I am a Ph.D. candidate at the School of Computer Science, Nanjing University of Posts and Telecommunications, supervised by Prof. Haiping Huang, and expect to graduate in June 2027. I obtained my B.E. degree from the same institution in 2021. My research interests include trustworthy AI, AI for software security, and differential privacy. From 2024 to 2026, I was a remote visiting Ph.D. student at Griffith University, working under the guidance of Prof. Leo Zhang and Prof. Yanjun Zhang.
