About Me

I am a postdoctoral researcher at Max Planck Institute for Informatics (MPI-INF), working with Prof. Bernt Schiele. I obtained my Ph.D. degree from Multimedia Lab (MMLab) of The Chinese University of Hong Kong (CUHK), supervised by Prof. Xiaogang Wang and Prof. Hongsheng Li. Before that, I received my bachelor’s degree from the Computer Science Honor Class of Harbin Institute Technology (HIT).

My research interests focus on computer vision and machine learning, particularly in exploring machine learning for autonomous systems. This includes 3D scene understanding, object detection, motion prediction, knowledge transfer, and other topics related to autonomous driving and robotics.
