My research interests lie primarily in ergodic theory and dynamical systems, and most of my work involves multidimensional symbolic dynamics. My research is supported by National Science Foundation grant DMS-1500685.

I am the current director of the DU Math Center; see http://www.du.edu/mathcenter/ or http://portfolio.du.edu/mathcenter/ for more information.
