About (the mathematical) me

I am a Ph.D. candidate in the Math Department at UC Davis. My advisor is Greg Kuperberg. My thesis work lies at the intersection of computational complexity and 3-manifold topology. I am also collaborating with Harry Baik on a geometric group theory project. I am broadly interested in 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: YouTube.
