About

Hi, I'm Kenji Tojo (東條建治), a Ph.D. student at the Creative Informatics Department of the University of Tokyo, advised by Prof. Nobuyuki Umetani.

I study computer graphics, and I'm especially interested in the application of inverse rendering techniques to the geometric design and computational fabrication problems.
