Dongqi Han's homepage

I’m an 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 trustworthy AI, anomaly detection, network traffic analysis, and other intersections between security and machine learning.
