I am a RTH-ITF Postdoctoral Fellow at the Department of Mathematics and the Center for Mathematical Artificial Intelligence (CMAI), The Chinese University of Hong Kong (CUHK). I obtained my Ph.D. degree from the Nanjing University of Aeronautics and Astronautics (NUAA). My research interests cover computer vision, deep learning, and artificial intelligence, with a focus on Geometric Deep Learning. I am also interested in their applications in Trustworthy AI and Science AI. My current work attempts to give new designs of invariant representations — from global to local and hierarchical assumptions. My research has appeared in several top-tier journals and conferences, such as TPAMI, ICCV, and USENIX Security.
