I am an assistant professor in School of Computing and Augmented Intelligence at Arizona State University. I am generally interested in deep learning, representation learning, and dynamical systems.

Open positions: I am looking for self-motivated Ph.D. research assistants. Email me with your CV and a brief introduction of your research interests to kookjin.lee@asu.edu.
