I am a fifth-year graduate student in mathematics at Columbia University, advised by Aise Johan de Jong. I was previously supported by an NSF Graduate Research Fellowship. Before that, I graduated from MIT in June 2015 with an S.B. in mathematics and minor in music.
I'm broadly interested in algebraic geometry. Some specific things I like thinking about are:
Moduli spaces of curves and branched covers (Hurwitz spaces), and their intersection theory
Brill-Noether theory, limit linear series, and related enumerative problems
Combinatorial aspects of the above, e.g. Schubert calculus
Syzygies of curves
Interpolation of curves in higher-dimensional varieties
Linear systems of singular divisors, e.g. the SHGH conjecture and related problems
Here are my papers:
Enumerating pencils with moving ramification on curves, arXiv 1907.09087.
The class of the d-elliptic Locus in genus 2, arXiv 1907.08991. Here is a video of my talk at ICTP on this work. Update (December 2019): I am in the process of completely rewriting this paper to include new results in higher genus and for pointed curves; please e-mail me if you'd like a detailed status update.
