I am an associate professor of Artificial Intelligence and Computer Science at POSTECH, and a faculty member of POSTECH Computer Vision Lab. I did a post-doc with Dr. Ivan Laptev and Prof. Jean Ponce in the WILLOW team at the Department of Computer Science of the École Normale Supérieure and Inria Paris. I completed my BS and PhD at POSTECH where I worked with Prof. Joon Hee Han and Prof. Bohyung Han.
My research lies in computer vision and machine learning. I am particularly interested in developing vision models that perform well even in uncontrolled environments in the real world. To this end, my recent work has focused on open-set/domain recognition, robustness against adverse conditions, and learning with limited/noisy labels or biased data.
