  • Research Interests
    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.
  • Teaching
    Fall 2024: COSC 149 All about Planar Graphs (syllabus)
    Winter 2025: COSC 30 Discrete Mathematics (old syllabus)
    Spring 2025: COSC 39 Theory of Computation
