I am currently an assistant professor at Brown University. My work is partially supported by an NSF postdoc (DMS-1902743). 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. I am currently particularly interested in the geometry of algebraic curves and applications of geometric methods to the study of rational points.

Here is my CV.

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.
