My research is on applications of discrete math, most often in the realm of coding theory. My PhD research was completed under the supervision of Dr. Christine Kelley at the University of Nebraska-Lincoln in 2014.

In 2016 I received a Villanova University Summer Grant to support my research.

I have also worked on the following projects with Villanova students:

  • Anthony Petrosino and Alissa Schembor: Counting profiles from rectangular tilings, Spring 2020.
  • Justin O’Pella (MA student): Locally recoverable codes from planar graphs, 2018-2019
  • Sally (Robertson) Ahrens (MA student): Enumerating tilings, summer 2016
