I am a graduate student in a Ph.D. program in the Computer Science Engineering department (CSE) at POSTECH, South Korea. My primary research interest is in learning visual correspondence and its applications. I am also interested in equivariant representation learning and burst image enhancement/restoration. I am a member of the computer vision lab. in POSTECH, under supervision of Professor Minsu Cho.
