Natasha Gelfand
Research ScientistVisual Computing and User Interfaces
Background
I graduated from Stanford University in 2006 with a Ph.D. in computer graphics. My research was on methods for analysis and registration of 3D shapes. I joined NRC in December of 2006, working in the Visual Computing and User Interfaces group. My interests are in geometry processing, shape and image matching, computer vision and computational photography.
