Research

​

​

-I study tensor categories, representation theory and higher-dimensional algebra. Questions I am interested in are typically 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).

​

-My research is supported by NSF Grant DMS-1901082.
