Research

I am mainly interested in number theory and arithmetic statistics, particularly questions related to elliptic curves, Selmer groups, and counting number fields. I am also interested in prime number races, special values of L-functions, effective estimates, and some related topics in combinatorics.

The following are my papers and preprints.  I have linked to journal versions where possible; preprints of all of papers can be found on arXiv.

I have also worked in computational genomics. The papers and abstracts below are the result of collaboration with Eli Van Allen, David Liu, and others at the Dana-Farber Cancer Insitute. My contributions primarily dealt with applications of non-negative matrix factorization to problems about mutational signatures. Check out related work from the Van Allen Lab. Though this is not my current research focus, I am very interested in revisiting some of these ideas with topological methods. Research from this work can be found at PubMed or on Google Scholar.  Here are the highlights:

Other Stuff

In April 2025, Louis Gaudet, Josh Stucky, and I organized  a special session on "Counting and Asymptotics in Number Theory" at the Spring Eastern AMS Sectional Meeting.

In December 2023, Jiuya Wang and I hosted a number theory conference, PANTS XXXVII, at UGA. 

For many years I organized the Tufts University Directed Reading Program (DRP). As a postdoc, I participated in the Spelman-Morehouse DRP. 

From Spring 2019 to Fall 2021, I organized  the Tufts Math Graduate Student Seminar, which is now run by J.C. Wang.
