CV / GitHub / Google Scholar / Zhihu / Email: |

I am a PhD student in Department of Computer Science, The University of Hong Kong (HKU) since 2019, supervised by Prof. Ping Luo and co-supervised by Prof. Wenping Wang. I also work very close with my friend Wenhai Wang and Prof. Chunhua Shen. I obtained B.S. from Nanjing University of Aeronautics and Astronautics (2016) and M.S. from TongJi University (2019). From 2018 to present, I collaborated with several researchers in industry e.g. Face++(Megvii), SenseTime, Facebook(Meta), Huawei and NVIDIA.

My research interest is computer vision in 2D/3D. I did some works on instance-level detection and self/semi/weak-supervised learning. I developed a few well-known computer vision algorithms including PolarMask, which was selected as CVPR 2020 Top-10 Influential Papers. I co-developed OpenSelfSup (now mmselfsup)(1k+ star), a popular self-supervised learning framework.
