I am currently a Postdoctoral Fellow at the Department of Data Science, City University of Hong Kong (CityU). Prior to this, I was a Postdoctoral Fellow at The Chinese University of Hong Kong (CUHK). I obtained my Ph.D. from Nanjing University of Aeronautics and Astronautics (NUAA). My research spans computer vision, deep learning, and artificial intelligence, with a particular focus on Geometric Deep Learning. My current work investigates novel designs of invariant representations — from global to local and hierarchical assumptions. My research has been published in top-tier journals and conferences, such as ACM Computing Surveys, IEEE TPAMI, IEEE TIP, ICCV, and USENIX Security.
