Curriculum Vitae  

I am a postdoc at Dartmouth College in Hanover, New Hampshire, working under the supervision of Asher Auel. In Fall 2023, I was based at the Hausdorff Research Institute for Mathematics in Bonn, Germany as a participant in the Junior Trimester Program in Algebraic Geometry. I received my PhD in 2020 under the supervision of Anthony Várilly-Alvarado.

In Fall 2023, I co-organizined the STReTCH seminar in Bonn with Xuqiang Qin.

Research Interests
General interests: Algebraic Geometry, Arithmetic Geometry, Number Theory

Specific interests: Hyperkähler varieties, cubic fourfolds, K3 surfaces, moduli spaces of these varieties, geometry over nonclosed fields, rational points


Kodaira dimension of moduli of special K3^[2]-fourfolds of degree 2 (2023, in Journal des Mathématiques Pures et Appliquées). Associated code. Journal version.

A census of cubic fourfolds over F2. (submitted, with Asher Auel, Avinash Kulkarni, Jonah Weinbaum). Associated code.

On decompositions for Fano schemes of intersections of two quadrics (submitted, with Pieter Belmans, Jishnu Bose, Sarah Frei, Benjamin Gould, James Hotchkiss, Alicia Lamarche, Cristian Rodriguez Avila, Saket Shah).

Zeta functions of K3 categories over finite fields (preprint, with Asher Auel ).

Rational points on modular curves of composite level (preprint, with Catalina Camacho Navarro, Wanlin Li, Jackson Morrow, David Zureick-Brown).

Sections of quadric fourfold bundles over surfaces (with Asher Auel ). In preparation.

Old stuff

Some random incomplete notes that some people have occasionally found useful.

Fun stuff Some non-mathematical activities that I enjoy: cooking, singing, hiking, biking, and skiing.
