About Me

I am currently a senior researcher at Samsung Research China - Beijing (SRC-B). I obtained M.S. degree in Electronic Science and Technology in 2019 from the school of Guizhou University. My research interest is to solve challenging problems in image restoration and face recognition. I have won multiple championships about image restoration in the CVPR competitions. My current work mainly focuses on image restoration, image generation and face clustering.
