I am a fourth-generation Kentucky educator, and I currently serve as visiting assistant professor in the School of Natural Sciences at the Indiana University - Southeast. I previously served as assistant professor of mathematics at the University of Louisville.

Before coming to the Louisville area, I was a graduate student at Cornell University, completing my Ph.D. in 2005 in probability theory and analysis under the direction of Laurent Saloff-Coste. Before that, I was an undergraduate in mathematics at the University of Kentucky, and a master’s student in mathematics at the University of Louisville.

I have a variety of interests related to mathematical research, and some of my papers are listed below. I am interested in random walks on infinite graphs, mathematical models of disease epidemics, and social choice theories of preference aggregation, collective choice, and voting. In each of these areas, there are aspects of the work which are readily accessible to undergraduate students and which could lead to undergraduate research projects.

I am also interested in the development of best-practices for utilizing new technologies to improve student learning.

I have developed a bank of conceptual clicker questions to be used in College Algebra, which are posted with the clicker resources at the Mathquest web-site. I wrote a case-study about how I use these questions to foster critical thinking and improve student communication skills, which is available at the i>clicker website. The style of these questions follows after the Cornell GoodQuestions for Calculus project.

I teach my courses using a tablet PC, adding pen-strokes to the screen as if it were a blackboard in the Microsoft OneNote program. I can record all the action using a screen-capture software called Camtasia Studio. I have previously used a different program called Tegrity. Here is a recently posted video of extra examples on Markov Chains.

I have recently began providing extra video examples for my classes using a LiveScribe pen. View this file in Adobe Reader X to see what these videos look like.
