Research Interests

I am interested in arithmetic statistics, the study of the distribution of arithmetic objects including primes, number fields, points on varieties, and families of equations.

Lately, my research has centered on questions of the form how often does an equation of a given shape have (certain kinds of) solutions? Some "shapes" of equations I find myself think about include hyperelliptic and superelliptic curves, hypersurfaces in projective space, and stacky curves arising from generalized Fermat equations. The solutions of interest are typically rational or integral points, but higher degree points and local (i.e. p-adic) solutions are also interesting.

You can read my research statement here.
