In my non-mathematical life I race bikes, go hiking and do a lot of yoga.

My main mathematical interests are in arithmetic geometry, representations of finite groups, and the arithmetic of orthogonal polynomials. My current research focuses on the torsion structure of abelian varieties and the arithmetic of orthogonal polynomials. I also have side interests in mathematics and politics (voting theory).

Some of my favorites:

Serre's Minerva lectures 1, 2, and 3 and Serre on Writing Mathematics Badly

Katz's IHES colloquium

The FLT Conference.

Some of my senior thesis students have gone on to pursue graduate degrees in mathematics: Andrija Perunicic (Bard '08, PhD Brandeis), Mona Merling (Bard '09, PhD Chicago), Anastassia Etropolski (Bard '11, PhD Emory), Galen Dorpalen-Barry (Bard '15, PhD student at Minnesota), Rylan Gajek-Leonard (Bard '16, Cambridge Part III, PhD student at UMass).

Most of my teaching material is on Moodle, but here are a few additional things I've written up for students: Steinberg Representation, Discriminant Lemma, Vector Calculus Handout.
