My primary research interests are in ergodic theory and dynamical systems, especially on *p*-adic and Berkovich spaces. My current work examines the ergodic properties and orbit equivalence classes of *p*-adic transformations. My interests for future work include analogues of results from complex dynamics and applications to arithmetic dynamics. For more information on my current research, see my research statement.

The following papers contain research that I participated in as an undergraduate. The first paper was completed as part of an REU at Oregon State University. The last two papers are on research completed while I worked in Kerry Kuehn's physics lab at Wisconsin Lutheran College.
