## Teaching

Right now, I'm a visiting professor at Columbia and not teaching.

Last semester (fall 2017) I taught:

- Math 343, "applied number theory", which focuses on public key cryptography.
- Math 380, "algebra", graduate algebra.

In previous semesters I've taught statistics, probability, linear algebra, calculus, multivariable calculus, algebraic topology, homological algebra, homotopy type theory, equivariant stable homotopy theory, and analysis in various forms (at the University of Chicago, Stanford, and here).
