Kim Youwang I am a Ph.D. student at AMILab at POSTECH, advised by Tae-Hyun Oh. I am also a research scientist intern at Meta Reality Labs - Codec Avatars team, working with Chen Cao, Yaser Sheikh, and Jovan Popović. I have a close research collaboration with Gerard Pons-Moll, and was a visiting researcher at Real Virtual Humans Group at the Univ. of Tübingen. I received my bachelor's degree in Electrical Engineering from POSTECH.

I work on research projects at the intersection of computer graphics, vision, and machine learning. My research interests are the generative modeling of 3D/4D virtual humans, animals, and objects by understanding their realistic shapes and appearances.
