About Me

I am a researcher at Beijing Academy of Artificial Intelligence (BAAI). I received my PhD degree from The University of Adelaide, supervised by Prof. Chunhua Shen. Before that I obtained my Bachelor degree from Tongji University. I have spent time at Megvii (Face++), Tencent, ByteDance, and NVIDIA. I am a recipient of the Google PhD Fellowship in 2021.

My research interests lie in the area of computer vision and machine learning, especially in enabling machines to see and understand the environment. Specific research topics include visual perception (2D/3D/video object detection and segmentation), and representation learning (self-/semi-/weakly-supervised learning).
