## Teaching

In Fall of 2015 I am teaching **Topics in Logic: Model Theory** (PMath 930) and **Groups and Rings** (PMath 347).

## Research interests

Model theory (a branch of mathematical logic).
Especially interactions with algebra, geometry and number theory.

*Three recent applications of model theory* is a short exposition I wrote for MSRI's Spring 2014 newsletter, The Emissary.

Here is a link to the logic group homepage at Waterloo.
