Will Dana's home page

I am a fifth-year PhD student in the Department of Mathematics at the University of Michigan, Ann Arbor.
I graduated in 2017 from the University of Washington, Seattle, with a B.S. in mathematics and a minor in music.

I am broadly interested in combinatorics and representation theory. Specifically, I'm currently studying relationships between Coxeter groups, quiver representations, and representations of preprojective algebras. My advisor is David Speyer.
I've also looked at Brascamp-Lieb inequalities, integral inequalities associated to certain quiver representations, with Harm Derksen.
More broadly, I enjoy any math that involves pictures with arrows in them. Combinatorics and representation theory both fit the bill.

At the University of Washington, I was the TA for the second-year honors calculus sequence in 2015-2016 (Math 334, 335, 336) and 2016-2017 (Math 334, 335, 336).


In summer 2019, I was a mentor at Canada/USA Mathcamp. I taught classes on complex projective space, ring theory, quiver representations, and determinants, as well as two- and one-day classes on random spanning trees and matroids.
Here are notes for my class on quiver representations.
Here are notes for my class on determinants.
Here is a note on why the groundskeeper's algorithm for generating uniformly random spanning trees works.
Here are notes on my one-day class on matroids.

UM grad student minicourses

In summer 2020, I ran a grad student minicourse on representations of finite-dimensional algebras, following Auslander, Reiten, and Smalø's Representation Theory of Artin Algebras. Here are the slides from the course.
In summer 2021, I ran a grad student minicourse on Ringel-Hall algebras, following Kirillov's Quiver Representations and Quiver Varieties.
Here are the slides from the course.
In summer 2022, I'm organizing the grad student minicourses. See this page for details. Feel free to contact me with logistical questions, or to get email notifications if you're not a current U-M grad student.

Michigan Math and Science Scholars

In the summers of 2020 and 2021, I was a TA with Doug Shaw's class on graph theory for the Michigan Math and Science Scholars program.
