My research is in topology, especially "diagrammatic algebra". You can find my papers on the arxiv, and can look at my cv and other job related things. I almost always go to the topology and quantum topology seminars. I am on the committee for UCSB reads.
Here is a syllabus for Math 4A that I taught in Fall 2014. (People still ask me for a copy sometimes.)
In Winter 2016 I gave a talk at a conference in Iowa.
Once upon a time I wrote a c program to search for an element of the kernel of Burau4 — it is poorly commented and not maintained. I also wrote a description of braid groups for non-experts.
I live in Santa Barbara with Morgan, Romeo, and Zoë. I like to make little toy web apps, for example: a clock, a text adventure game, and a minimalist message board.
Here is a page of links.
