I received my BS in 2011 and MS in 2013 at Electrical Engineering, KAIST. As of 2013, I am a PhD student at KAIST, working on visual representation learning with Prof. In So Kweon, but I decided to take some time off to join Lunit in 2017. As a full-time research scientist at Lunit, I am devoted to developing advanced AI for medical image analysis and interpretation via cutting-edge deep learning technology. During my internship experience at Adobe Research in the US, I worked on large-scale video representation learning. My research interests include visual recognition problems with deep learning approaches.

Research Interests

Representation learning, unsupervised learning, large-scale learning, for visual recognition.
