I am a Ph.D. student supervised by Prof. Luc Van Gool at Computer Vision Laboratory, ETH Zürich. I also work closely with Dr. Kai Zhang and Dr. Yulun Zhang. My main research interest is the low-level vision, especially on the image and video restoration, such as super-resolution, deblurring and denoising. Besides, I enjoy applying mathematics in proposed methods. Recently, I have some paper published in NeurIPS, ICML, TPAMI, CVPR and ACML. I served as the reviewer for several top-tier conferences, such as NeurIPS, ICLR CVPR and AAAI, etc.
