My primary research interests involves the application of dynamical systems
(uniformly hyperbolic, partially hyperbolic, symbolic, tiling) to mathematical physics, as well as studying dynamical systems arising from mathematical physics. I use dynamical techniques to investigate spectral properties of operators involved in the study of quasicrystals. I'm also interested in conducting numerical experiments related to the long-term behavior of several models.

Another one of my research interests lies in number theory and integer sequences.
Think of a number, now square the digits and sum that. What do you get?
If you keep iterating this procedure, you will either end up at a 1 or a 4.
If you end up at a 1, the number you started with is called a happy number.
I study several generalizations of this procedure.

I've also done a bit of work on explanation as it relates to epistemology and cognitive science of mathematics
and a spatial sampling analysis on a synthetic mollusk
I've supervised several undergraduate student projects in the above areas at Denison:
