Research Interests:

I am a number theorist with an eye to finding and answering surprising properties of deceptively elementary constructions. My research currently focuses on the higher composition laws of Bhargava and his students and on reflection theorems of Ohno-Nakagawa type, with applications to arithmetic statistics and the study of Shintani zeta functions. In my research, I use such tools as Fourier analysis on adelic cohomology (in the style of Tate's thesis) and the combinatorial aspects of p-adic algebra (e.g. Igusa zeta functions).
