What I do

I teach mathematics, conduct research in topological dynamics, and provide service to the University of Denver. I am currently serving as the Undergraduate Coordinator for the Mathematics Department.

Professional Biography

I grew up in Beltsville, MD. I earned a BS in mathematics the University of Delaware, a PhD in mathematics at the University of Maryland. I held postdoctoral positions at the University of Texas and the University of Connecticut before joining the University of Denver in 2002. Currently, I am associate professor in the mathematics department. My research is in topological dynamics, and more specifically on continuous actions of the Cantor set.
