In Winter 2017 I will be teaching Math 108B. Go to Gauchospace if you are a 108B student looking for information about the course. I was on the UCSB reads committee. Here are the UCSB reads events.

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. Here is the topology seminar schedule.

### Ancient history

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 taught Algebraic Topology – Math 232A, and 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 once wrote a description of braid groups for non-experts.

### Personal

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 picture of strawberries.
