Research Interests

My research interests are in the field of dynamical systems and ergodic theory. In dynamical systems, we study how systems evolve under repeated iteration of a single function. Past work of mine includes the study of convergence for specialized ergodic averages.

My recent research has been in the area of cellular automata. A priority of mine is to incorporate students in various research projects. Last summer, I worked with Sarah McRoberts to investigate a model used to describe the competition for rock space between two intertidal species.

This summer I will be working with a couple of Luther students to investigate a model to understand the frequency of various sized avalanches in a sandpile.
