Short CV

As of January 2023, I am an Assistant Professor in the Department of Mathematics in Universidad Católica de Chile.

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. In 2018, I received my PhD in Mathematics from the University of Washington.

Research Interests

Algebraic and Arithmetic Geometry: Algebraic stacks and applications, vector bundles, moduli spaces, Brauer groups, twisted sheaves, the resolution property, and arithmetic hyperbolicity.
