Note to undergraduates: I am not planning to take any undergraduates for research or reading courses at this time.
Almost all of my past courses are on Canvas.
I frequently teach Math 110 (formerly Math 144), which is our introduction to proofs course. Sarah Yeakel and I co-developed the current version of course. I am happy to share my notes and other materials upon request. They have evolved past the material contained on this website, but I am keeping those up in case they are useful to others.
In Fall 2022, I taught a graduate topics course on hierarchically hyperbolic spaces, in which I presented a new proof of the cubical model theorem of Behrstock-Hagen-Sisto. There are videos, and I would be happy to share them upon request.
