# Will Dana's home page

I am a soon-to-be-third-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.

## Research

I am broadly interested in algebraic varieties that come from linear algebra and representation theory, as well as combinatorial structures related to them. I am currently studying quiver representations with David Speyer. I've also been looking at Brascamp-Lieb inequalities, integral inequalities associated to certain quiver representations, with Harm Derksen.

Some things I'd like to learn more about are subspace arrangements, flag varieties, geometric invariant theory, and representation stability. More casually, I also enjoy learning about category-theoretic perspectives on things.

## Teaching

### UM

Fall 2017: Math 105.

Winter 2018: Math 115.

Fall 2018: Math 116.

### UW

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).
### Other

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.

Please let me know if you find typos.
## Miscellany

Outside of math, I enjoy puzzles and games, music (in particular electronic music), and baking.

I was interviewed for this article about the Putnam exam at UW.
