Teaching Schedule

I am teaching Calculus I, Linear Algebra, and Statistics during Spring 2009. I am supervising two undergraduate students who are working on sum graphs, one student studying preferential attachment graphs, and co-supervising a student who is making great progress on problems related to queens separation.

Personal

I like music, movies, hiking, canoeing, and building stuff. I love to read, especially mathematics and philosophy. I also like art. Check out the work of Santha Gwyn.
