As of August 2025, I am an Assistant Professor at the University of Georgia.
I am currently on leave from my previous position at the Universidad Católica de Chile. I received my PhD from the University of Washington in 2018 and from 2018 to 2022, I did postdocs at the University of Arizona, Heinrich-Heine Universität, the Mittag-Leffler Institut, and the Institut de Mathématique d'Orsay.
Algebraic and Arithmetic Geometry: Algebraic stacks and applications, Formal GAGA, vector bundles, flat cohomology, moduli spaces, Brauer groups, twisted sheaves, the resolution property, and arithmetic hyperbolicity.
