Short bio
I am an Associate Professor at the School of Electrical Engineering at KAIST, jointly affiliated with School of Computing. I completed my Ph.D. in Electrical Engineering and Computer Science (EECS) at MIT in 2014. From 2014 to 2017, I worked at University of Michigan as a research fellow. I received my M.S. from MIT, and my B.S. (with summa cum laude) from KAIST in Korea, all in the Department of EECS.
My research interests include data science, information theory, statistical inference, machine learning, and quantum information. I want to provide theoretical framework to data science by using tools from information theory, statistical inference and machine learning. I also aim to develop efficient algorithmic tools in extracting and exploiting information in statistical inference problems.
