Research Focus
Most of my creative work has been in writing educational mathematics software. I have interactive ODE solvers, PDE solvers, IFS makers, a linear algebra program, and various other things available on my web page. These are directed primarily to undergraduates, and the purpose of them is to let the student learn by exploring.
