I am a Computer Science Ph.D. student at University of Maryland, College Park (UMD), working with Prof. Dinesh Manocha at the GAMMA Lab

At UMD I've worked on computer vision and autonomous navigation systems. I did my MS at KAIST, where I was advised by Changick Kim. I did my bachelors at the KAIST.
