👨🏼‍🎓 About [中文]

I’m an associate researcher (assistant professor) at the Beijing University of Posts and Telecommunications (BUPT). Before that, I received my Ph.D. from Tsinghua University in 2024, advised by Prof. Zhiliang Wang, and also a joint Ph.D. at Nanyang Technological University advised by Prof. Yang Liu. My research focuses on the intersection between AI and Cybersecurity.
