Suha Kwak

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 efficient learning, robustness, and fairness of vision models, and their application to comprehensive video understanding and multi-modal perception.
