Biography

I am currently a Professor in the College of Cyberspace Science and Technology, Beijing University of Technology (BJUT). Before joining BJUT, I was an assistant professor at the State Key Laboratory of Multimodal Artificial Intelligence Systems, Institute of Automation, Chinese Academy of Sciences (CASIA). I received my Ph.D. from USTC and CASIA in June 2024. My PhD supervisor is Prof. Changsheng Xu (IEEE/IAPR/CCF/CSIG Fellow). Before that, I obtained a Bachelor in telecommunication engineering from BUPT in June 2019.
