Research

My research interests are in the areas of computational geometry and mesh generation. I have been working on the design, analysis and implementation of geometric data structures and algorithms with applications to computer graphics, in particular, efficient realistic rendering.

I am interested in various issues related to hierarchical simplicial meshes, including pointerless representations, efficient neighbor-finding, different subdivision techniques and quality guarantees associated with them, and level-of-detail modeling.

I am also interested in understanding motion from a computational geometry point of view. I am working on creating a probabilistic framework for kinetic data.
