One of my research interests involves the application of dynamical systems
(uniformly hyperbolic, partially hyperbolic, symbolic) to mathematical physics.
Specifically, 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 longterm behavior of several specific dynamical systems.

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.
