I am a fifth year graduate student interested in mathematical physics. I work on problems in the intersection of combinatorics, algebraic geometry and probability. I am visiting Yale for the academic year 2019-2020. My advisor is Rick Kenyon.
I am an organizer for the Brown discrete math seminar with Rick Kenyon and Sam Watson. I am also an organizer for the AMS annual grad student math conference at Brown with Victoria Gras Andreu and Max Weinreich.
- Dimers and Beauville systems. (in preparation; with Alexander Goncharov and Rick Kenyon.)
a convex integral polygon, we can construct a dimer integrable system
and a toric surface. We show that the spectral transform is a birational
isomorphism of the dimer integrable system with the Beauville integrable
system associated to the toric surface.
- Cluster modular groups of dimers and networks. (with an appendix by Giovanni Inchiostro.)
We compute the group of symmetries of the dimer integrable system. Each element of the group gives a way to shuffle the dimer model, generalizing domino-shuffling.
- Spectra of biperiodic planar networks.
Associated to the Laplacian on a biperiodic planar network is its spectrum, a curve and a certain divisor on it (see image below for an example depicting the divisor on the amoeba of a spectral curve). We provide a classification of biperiodic planar networks in terms of their spectrum.

Cube groves are a model for random surfaces. In the scaling limit, they exhibit phase transitions where the phase boundary is a deterministic algebraic curve (see image below).
