About (the mathematical) me

I am a visiting assistant professor in the UC Santa Barbara Math Department. I recently earned my Ph.D. from the Math Department at UC Davis. My advisor was Greg Kuperberg.

Much of my focus, including my dissertation research, is on the intersection of computational complexity and 3-manifold topology. I am also collaborating with Harry Baik on a geometric group theory project. Broadly, my interests are geometric topology and group theory, quantum algebra, and computational complexity and quantum computing.

Here's my CV. Here's a very full, loose lamination with \(\mathbb{Z}/4 * \mathbb{Z}/3\) symmetry:

And here's a video of a talk I gave at the University of Warwick related to my dissertation work: YouTube.
