About
My current research interests revolve around discrete/computational topology and geometry and connections to efficiency of computation. I usually find simple objects (like polygons, curves, planar graphs, surfaces and meshes) cute and attracting.
Well, actually, anything with the word "algorithm" or "topology" catches my attention.
