# Activism

- More Linear Algebra, Please, from the AMS Blog On Teaching and Learning Mathematics

# Expositions

- Lots of good expositions here.
- I was writing a book called "What is ADE?" but it's on pause. Here's the beginning.
- My PhD is sort of like a book: Generalized noncrossing partitions and combinatorics of Coxeter groups, 2009.
- Braid groups, clusters and free probability, outline from an AIM workshop, Jan 2005.
