My research interest lies at the intersection of Image Processing, Computer Vision, and Machine Learning. In particular, my work focuses on understanding different aspects of visual information in images and videos, including texture, resolution, color, motion, depth, geometry, illumination, etc., and developing algorithms to reconstruct and enhance them. My work includes BlindSR, RawSR, QVI, RSC-Net, and Texformer.
Short bio: I was a Research Fellow at Nanyang Technological University from 2020 to 2021. I did my postdoc at Carnegie Mellon University and Massachusetts Institute of Technology from 2019 to 2020. I got the Ph.D. degree in the Department of Electronic Engineering at Tsinghua University in 2018. Before this, I received my B.Eng degree in the Department of Electronic Engineering at Tsinghua University, and my B.Ec degree in the National School of Development at Peking University. I was a visiting scholar at University of California, Merced and Harvard University. I have been fortunate to work with Yu-Jin Zhang at Tsinghua, Ming-Hsuan Yang at UC Merced, Deqing Sun and Hanspeter Pfister at Harvard, Fernando De la Torre, Francesc Moreno-Noguer, and Laszlo A. Jeni at CMU, George Barbastathis at MIT, Chen Change Loy at NTU, Shuicheng Yan at Sea AI Lab. I am an Area Chair of CVPR 2023 and have served on the Senior Program Committees of AAAI 2023 and IJCAI 2021.
I am open to collaborations in a broad area of computer vision. Please drop me an email if you are interested.
