Gustavo T. Pfeiffer
Currently I am a Ph.D. candidate in Information and Communication Engineering at
the University of Tokyo, supervised by
Prof. Yoichi Sato.
Previously, I did
research for many years at the Computer Graphics Laboratory (LCG),
of COPPE-UFRJ, as a M.Sc.
student from PESC-UFRJ and as an undergraduate research student
during my graduation in Computer and Information Engineering at UFRJ. Before entering LCG, I had also
worked with Petroleum Reservoir Engineering at LABMA-UFRJ.
My research encompasses various themes within computer graphics and vision, including 3D reconstruction, physically-based appearance modeling and vision-based interaction. Currently I am working on stochastic optimization methods for inverse problems in computer graphics.
