Here is my Curriculum Vitae


I am interested in most forms of number theory and geometry. My main focus is analytic and algebraic number theory. I also enjoy convex geometry and its applications. I am particularly fond of function fields and local fields. I have worked with Galois groups, class groups, quadratic forms, and applications of Poisson summation. My thesis research is in classifying pairs of polynomials f(X), g(Y), so that f(X) = g(Y) has infinitely many rational solutions. This work is based on papers of R.M. Avanzi and U.M. Zannier, as well as Bilu and Tichy, Michael Fried, and Ritt. Much of my work has been in density theorems, and probabilistic number theory. I am also doing research in additive number theory, and some circle method techniques. I enjoy sieve methods, although I have not done any original research in these areas. I also enjoy ergodicity, in particular Mahler measure. My graduate advisers were Michael Zieve, and Jeffrey Lagarias.

My Student(s)

I have advised one masters student to date. Douglas Weathers graduated in Spring 2015 with the thesis Decompositions of the Kuchment-Lvin Polynomials.
I have also advised Addison Labonte (class of 2016) on her senior honors thesis about multi-magic squares and sudoku.


I am currently teaching Linear Algebra I (MAT 262)

I am also teaching Calculus III (MAT 228)

Previously at UMaine I've taught

- MAT 126 (Calculus I)

- MAT 563 and MAT 564 (the graduate algebra sequence)

- MAT 228 (Multi-Variable Calculus)

- MAT 261 (Introduction to Proofs)

- MAT 463 and MAT 464 (Undegraduate Abstract Algebra)

In my free time I enjoy playing bridge. In the summer of 2009, four Michigan students and I won the Grand National Teams in flight C. You can read about it here. I have previously spent many years tap dancing, performing some theatre, and volunteering as an EMT. These days most of my free time is spent chasing my son, Joel, and daughter, Shoshanah. My wife's photoblog can be found here.
