Changil Kim

I am a Research Scientist at Meta, where I work on research projects at the intersection of computer graphics, vision, and machine learning. Previously, I was a postdoctoral fellow at MIT CSAIL and ETH Zurich in Switzerland. I received a PhD in Computer Science from ETH in collaboration with Disney Research.

I received the Swiss National Science Foundation Postdoctoral Fellowship, the Sony Focused Research Award, and the credits in Disney movies for the work I did on 3D scene reconstruction.
