Research

Most of my work is in the general area of quantum algebra, motivated by applications in mathematical physics. The mathematical objects I think the most about are tensor categories and operator algebras, and how they interact through generalized symmetries. Recently I have been very interested in using these tools to rigorously study quantum spin systems and topologically ordered phases of matter.
