I am an Assistant Professor in the Department of Computer Science and Engineering at Sogang University. Before joining Sogang University in Fall 2021, I spent two wonderful years as a Research Intern and then a Research Scientist at NAVER AI Lab, where I had the good fortune to work with Dongyoon Han, Sangdoo Yun, Seong Joon Oh, Sanghyuk Chun, Byeongho Heo, and Jung-Woo Ha. I obtained my Ph.D. from the Yonsei University in 2020 under the supervision of Prof. Hyunjung Shim, and my B.S. also from the Yonsei University in 2013.

Research Interests

My recent research interest are in building a machine that can robustly understand the visual world only with minimal human supervision. In particular, I am interested in learning from imperfect data, such as self-supervised, semi-supervised, and weakly-supervised learning for pattern recognition problems.
