In Fall 2022 I started my second year as department chair.
My research is in topology, especially "diagrammatic algebra". You can look at my list of publications, or preprints on the arxiv, or my infrequently-updated cv.
I keep a random collection of syllabi of courses I have taught. (Sometimes people need them for course transfers.)
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 live in Santa Barbara with Morgan, Jasper, Romeo, and Zoë.
