## About

I am a third-year PhD student in the Mathematics Department at UC Berkeley.
I graduated from the University of Virginia in 2015, and I passed my qualifying exam in August 2017.

You can find my CV here.
It was created with Simple CV.

## Research

I am broadly interested in topology, mathematical physics, and representation theory.
Another overly-broad descriptor is "quantum topology."
Some more specific topics are: knot invariants, tensor categories and/or (braided) monoidal categories, quantum groups, diagram algebras, topological quantum field theory.

This semester I'm organizing the GRASP student seminar.
You can also find the webpage for Fall 2017 here.

Are you a student who wants to do better on mathematics exams?
If so, you may find this advice useful.

As an instructor, I am typically responsible for computing and entering final letter grades.
After spending too much of my time wrangling with Excel spreadsheets at the end of the semester, I decided to write some Python to automate it for me.
If you'd like to look at it or use it yourself, the code is hosted on GitHub.
Comments are appreciated!

## Writing

What is Lie algebra cohomology and why should you care? In the literature, there are two approaches to proving things like Levi decomposition and complete reducibility: detailed proofs without much intuition, or a mention of cohomology and a citation of a book on homological algebra.
This document is an attempt at an intermediate approach.

## Personal

I was a member of the Jefferson Literary and Debating Society while a student at UVA.
Nowadays my non-mathematical pursuits are mostly restricted to playing mildly competitive ultimate (frisbee.)
