I am a Postdoctoral Researcher at Utrecht University, working as part of the XL Rational Points Consortium. Previously, I was a Ross Assistant Professor at Ohio State, working with Jennifer Park and a Gamelin Postdoctoral fellow at MSRI during Fall 2020. I graduated from the University of Wisconsin, Madison in 2020. My advisor was Jordan Ellenberg.

I am interested in Arithmetic Geometry, Arithmetic Statistics, and Rational points on moduli stacks.

 I am currently co-organizing the Algebraic Geometry seminar at Utrecht University, as well as the Arakelov Theory seminar of the Rational Points Consortium.

I co-organized a Mathematical Research Community on Explicit computations with Stacks in June 2023. I also co-organized the online seminar series, New Developments in Number Theory during the pandemic and a conference, Madison Moduli Weekend Online in September 2020. In June 2020, I led a mini-course at CTNT 2020 on curves over finite fields. In July 2021, I was involved in a fantastic workshop called Rethinking Number Theory.
