About Me

I am a third-year PhD student at Institute of Automation, Chinese Academy of Sciences (CASIA). I am a member of State Key Laboratory of Multimodal Artificial Intelligence Systems (MAIS), advised by Prof. Liang Wang and co-advised by Prof. Yan Huang. Prior to that, I obtained a B.Eng. in Automation from Harbin Institute of Technology (HIT).
