About Me

I am an Assistant Professor in the Department of Artificial Intelligence at Chung-Ang University. My work focuses on the mathematical and statistical foundations of machine learning.

Before joining Chung-Ang University, I was a postdoctoral researcher at the University of Milan, New York University, and the University of Arizona. I received my Ph.D. in Mathematical Sciences from KAIST under the supervision of Prof. Wanmo Kang.
