I enjoy doing research in algorithms, data structures, and computational geometry.  Some of the research topics that I have worked on include point location, approximate shortest paths, mesh generation, and reconstruction of surfaces and manifolds, and shape matchingI have written a book, Delaunay Mesh Generation, with Tamal Dey and Jonathan Shewchuk.  It is a thorough guide to Delaunay triangulation and mesh generation by  Delaunay refinement.
