Undergraduate Research

I attended Davidson College for undergrad, where I majored in math and minored in educational studies.

My first research project was with Axel Brandt, studying the additive choice numbers of graphs.

For my senior thesis, I studied zero forcing with the guidance of my advisors, Donna Molinek and Heather Smith. See below for more specifics!

I also worked on a project with Mindy Adnot on school choice and segregation in North Carolina. Here's a map of NC I made with all of the 2018 charter and magnet school data.

Zero forcing polynomials: mapping spiders to paths

Abstract

This paper explores zero forcing sets and zero forcing polynomials on simple graphs. We begin with a graph with all white vertices, and we choose a set of vertices of size i to color blue. We then iteratively apply a color change rule to our graph. If we can force the remaining vertices blue with this color change rule, then our initial set was a zero forcing set. The zero forcing polynomial of a graph G is a generating function, defined such that the coefficient on x^i is the number of zero forcing sets of G of size i. In "The zero forcing polynomial of a graph," where this polynomial was introduced, the authors conjecture that a path of length n has at least as many zero forcing sets of size i as any other graph on n vertices. In this paper, in addition to constructing new zero forcing polynomials, we prove that this conjecture holds for certain families of graphs, namely spiders.
