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.


Research

- Dimers and Beauville systems. (in preparation; with Alexander Goncharov and Rick Kenyon.)

- Cluster modular group of the dimer model. (in preparation; with an appendix by Giovanni Inchiostro.)

- 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.

- Grove arctic curves from periodic cluster modular transformations.

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).
