I am currently an associate professor at Brown University. My work is partially supported by NSF DMS-2200655. Starting in September 2024, I will be supported by NSF CAREER Award DMS-2338345. I received my PhD in June 2019 from MIT, where I was a student of Bjorn Poonen and Joe Harris. During the 2019-2020 academic year I was an NSF postdoc at Stanford University, working with Ravi Vakil. During the 2020-2021 academic year I was an assistant professor at The University of Washington.

My research is in the intersection of algebraic geometry and number theory, including the geometry of algebraic curves and rational and low degree points on varieties.

I firmly believe Federico Ardila's basic axioms:

  • Axiom 1. Mathematical potential is distributed equally among different groups, irrespective of geographic, demographic, and economic boundaries.
  • Axiom 2. Everyone can have joyful, meaningful, and empowering mathematical experiences.
  • Axiom 3. Mathematics is a powerful, malleable tool that can be shaped and used differently by various communities to serve their needs.
  • Axiom 4. Every student deserves to be treated with dignity and respect.
