My current research interests are in representation theory and algebraic geometry. My undergraduate research also focused on combinatorics.

Recently, I have been interested in differential geometry in positive characteristic and deformation quantization. I have also been thinking about classical questions about the representation theory of the general linear group.

In tropical geometry, I studied *tropical linear spaces*.
They are certain weighted polyhedral complexes: in that language, tropical linear spaces are tropical cycles of degree 1.
They may also be described algebraically as certain modules over the tropical semifield;
the analogous algebraic object over the Boolean semifield is exactly a matroid.
I hope to further develop this perspective by creating more analogies between matroids, tropical linear spaces, and generally matroids over hyperfields through the lens of module theory.
I am also interested in using tropical linear algebra to develop tropical ideals and tropical schemes.
