### About me

I am an assistant professor at the University of Maine. Previously, I was limited-term faculty at the University of Georgia working with the discrete analysis group, and before that I was a Chowla Research Fellow at Penn State, working with Bob Vaughan. Before that, I was a PhD student supervised by John Friedlander at the University of Toronto. View my CV.
My primary interests are number theory, combinatorics and harmonic
analysis, but I like a good problem from any branch of math. Outside of
math I like baseball, snowboarding, golf, playing the guitar and video
games. I am a fan of the Ottawa Senators and the Toronto Blue Jays.

### Research

I am interested in questions lying somewhere in the realm
of analytic number theory, additive combinatorics and harmonic analysis. I have a
particular fondness for questions about equidistribution, as well as (additive combinatorial) inverse problems. Below you can
find my preprints and publications.

### Teaching

I am currently teaching Math 261, Introduction to Abstract Mathematics. In previous semesters at UGA I taught Math 1113 (Precalculus) and Math 2250 (Calculus 1). At Penn State I taught Math 312 (Real Analysis), Math 110 (Techniques of Calculus), Math 141 (Calculus II) and Math 231 (Vector Calculus I).

In the summer of 2020, I gave a graduate lecture series on Fourier Analysis and Number Theory, with accompanying notes. These notes take from various references including Katznelson's An Introduction to Harmonic Analysis, Helson's Harmonic Analysis and Montgomery's Ten Lectures..., and Tao and Vu's Addtive Combinatorics. These notes may have errors.
