Research
My research interests lie within intersections of topology and algebra. Areas I am broadly interested in include:
- Homotopy theory
- Knot theory
- Quantum groups
- Geometric group theory
I'm particularly interested in exploring invariants of low-dimensional manifolds, from well-studied cohomology theories to new(ish) categorical invariants (such as Khovanov homology).
I've also come to realize that most people, including most programmers, are not comfortable with pure mathematics, and most pure mathematicians are not comfortable with systems-level programming. I'm comfortable with both, so if there's a problem where I can utilize my knowledge in both areas simultaneously, I'm typically interested in it.
