I direct the Motion and Shape Computing (MASC) Group that is affiliated with the GMU Autonomous Robotics Laboratory. Visit MASC group project page for our most recent research and publications.

Our research goal is to develop efficient, robust and practical algorithms for representing, manipulating and analyzing massive geometric data of shape and motion. Our research finds applications in the areas of computational geometry, computer graphics, GIS, visualization and robotics.

I also organize GRAND seminar. If you are visiting Washington DC area, I would certainly love to have you stop by and give a talk.
