My research interests are in combinatorial algebraic geometry with a particular focus on tropical and non-Archimedean geometry and the geometry of moduli spaces. I enjoy exploring its many surprising interactions with other areas of modern algebra, geometry, and topology, for example to the geometry of flat surfaces, to Brill-Noether theory, to enumerative geometry, to Hurwitz theory, and to geometric group theory (in the form of Bass-Serre theory and the geometry of Outer space). In order to relate the tropical world to the world of classical algebraic and arithmetic geometry I often draw from techniques in toric and logarithmic geometry, analytic geometry over Archimedean and non-Archimedean fields, as well as from deformation theory and the geometry of stacks.

My preprints are all on the arXiv. Feel free to check out my Google Scholar profile.
