# Research

I am broadly interested in algebraic geometry. Most of my time is spent thinking about Cremona groups, Galois cohomology, Fano varieties, groups acting on varieties, and representation theory. At the moment, I am working on a large project to classify the symmetries of del Pezzo surfaces.
