Bella Tobin

I am 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. 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.

I was a faculty advisor of the Oklahoma State University AWM student chapter

I am looking for a tenure track position starting in Fall 2023 or Fall 2024. I can provide my application materials upon request.
