I am an assistant professor in the mathematics department at Agnes Scott College.
My research interests are arithmetic dynamics and number theory. I am particularly (but not exclusively) interested in the connections between arithmetic dynamics and arithmetic geometry and the role of dynamical Belyi maps in arithmetic dynamics.
In 2022-2023 I was a postdoctoral scholar at Oregon State University working with Clay Petsche. From Fall 2019-Spring 2022 I was a post-doctoral fellow at Oklahoma State University working with Paul Fili. I received my PhD from the University of Hawaii in 2019 under Michelle Manes.
I was a faculty advisor of the Oklahoma State University AWM student chapter.
I believe that mathematics should be accessible, inclusive, and fun. I also know that math is difficult. Even if you don’t know the answer today, that doesn’t mean you won’t know it tomorrow. Math can show up in unexpected places, and I want my students to have the confidence to tackle mathematical problems in the real world. I am always happy to chat about how these views influence my courses.

Upcoming Talks
2/14: Georgia Tech Number Theory Seminar
3/9-3/11: Southern Regional Number Theory Conference
3/22: New Mexico State University Math department Colloquium

I am interested in speaking at number theory seminars and number theory conferences in 2024, especially in the southeastern US region.
