I have been a faculty member at Pacific Lutheran University for nine years. Before moving to Tacoma, I received a PhD after five years at the University of Notre Dame studying Coxeter groups with Matthew J. Dyer. Previously, I completed a Masters degree at Colorado State University working with Anton Betten, and I did my undergraduate work at Dickinson College. My mathematical interests lie in the relationship between representation theory and combinatorics of Coxeter Groups. I am also interested in partial orders, combinatorial number theory and integer sequences. More recently, I have become interested in visualization of mathematics (in particular so-called Proofs Without Words). Starting in January 2019, I will be the editor-elect for the MAA publication Math Horizons, and I will be the editor from 2020-2024.

Math Horizons

Starting in 2019, I will be the editor-elect of Math Horizons, the undergraduate magazine of the Mathematical Association of America. I will then serve as the editor for the term of 2020-2024.

From the Math Horizons website: Math Horizons is intended primarily for undergraduates interested in mathematics. Our purpose is to introduce students to the world of mathematics outside the classroom. Thus, while we especially value and desire to publish high quality exposition of beautiful mathematics we also wish to publish lively articles about the culture of mathematics. We interpret this quite broadly - we welcome stories of mathematical people, the history of an idea or circle of ideas, applications, fiction, folklore, traditions, institutions, humor, puzzles, games, book reviews, student math club activities, and career opportunities and advice.

Want to read Math Horizons? All MAA members get free electronic access to the magazine - just log in through the MAA website. Non-members can read all past issues (1993-present) on the Taylor & Francis site or at Jstor. There are also free articles available online:
