Jiaqi Xu

I am a Ph.D. student at The Chinese University of Hong Kong (CUHK). I am currently working on low-level vision. I am extremely fortunate to be advised by Prof. Pheng-Ann Heng and Prof. Qi Dou.
Previously, I received my M.Sc. in Information Engineering from CUHK in 2019 and B.Eng. in Biomedical Engineering from Beihang Univerisity in 2018.
