Assistant Professor of Mathematics

I am a mathematician specializing in graph theory, design theory, and combinatorics. I am especially interested in breaking apart graphs into smaller subgraphs with special properties. I have a BA in mathematics from Scripps College and received both my master’s and PhD in mathematics from Auburn University working with Chris Rodger. Prior to SUA, I was a postdoc at the University of Denver working with Paul Horn.

In my classrooms, I aim to create an atmosphere of discovery through a variety of techniques designed to activate students’ abilities to think critically. Rather than simply explaining the material, I challenge my students to see a problem and organically develop a process to solve it themselves, with confidence at efficiency. I teach a variety of math courses, but some of my favorites are discrete mathematics, graph theory, mathematics for liberal arts, and linear algebra!
