990 Lincoln Place Boulder, CO 80302 (970) 302-6315 (cell)I am currently living in Boulder, Colorado, and teaching at the University of Northern Colorado. My research is in geometry, logic, and formal reasoning with diagrams; you can find some of the papers that I've written here. Occasionally I think back on the halcyon days of my youth, spent at Cornell University , at Princeton University, and in Newtown, CT. If none of this seems sufficiently interesting to you, you could try looking here.
