Brief Bio
I am a PhD student at the Dept. of Electrical and Computer Engineering, University of Michigan, Ann Arbor, working with Prof. Silvio Savarese. My research interests include Machine Learning and Computer Vision with particular interests in human behavior understanding and multiple target tracking. I got my B.S degree in Electrical Engineering at Seoul National University before I moved to Ann Arbor.
