I work in number theory. Some of my particular interests:

- Classical analytic number theory. My first task in graduate school was to read all of Davenport. I am interested in sieve methods, L-functions, and related topics, and their classical applications -- as well as applications beyond their traditional settings.
- The distribution of number fields, class group torsion, and related topics. I am especially
interested in these from an analytic point of view involving
*Shintani zeta functions*associated to*prehomogeneous vector spaces*. I am also interested in other perspectives on these questions: class field theory and Kummer theory; the Scholz reflection principle; algebro-geometric perspectives on these topics; and other related perspectives.
