-My main research interests are in quantum algebra. In particular, I study tensor categories, representation theory and higher categories. Questions I am interested in are often motivated by applications in mathematical physics (topological phases of matter, conformal field theory, topological quantum field theory) or operator algebras (subfactors, compact quantum groups, noncommutative geometry).
