I am currently Craig McKibben & Sarah Merner Endowed Professor of Mathematics at the University of Washington. My work is mostly in algebraic geometry (of an arithmetic flavor), but lately I’ve also been thinking a bit about computer vision. Here is a (likely outdated) copy of my CV.


I mostly do math research. Here’s my listing on MathSciNet if you can access it. Here’s my listing on the arXiv, where I put all of my math papers (with a few exceptions from long ago, and one or two things that publishers won’t let me put there).

Here is a book manuscript with Kollár, Olsson, and Sawin: The Zariski topology, linear systems, and algebraic varieties.

Every once in a while, I do something else. I will try to keep the list of non-math articles up to date in my CV, but it is possible I will fail.


This year I’m teaching a course on model theory in algebraic geometry, in the Spring quarter.

Graduate program

I’m currently running the graduate program in the UW math department. Please go here if you want to schedule a meeting with me.
