About me

I study quantum symmetries in the form of tensor categories, higher categories and their applications in topological phases of matter, conformal field theory and operator algebras. 

I am currently a postdoc at the Ohio State University, with faculty mentor David Penneys. Previously I was a postdoc at the Australian National University under the supervision of Scott Morrison (2016-2018).​ I completed my PhD at Vanderbilt University under the supervision of Vaughan Jones in 2016. I'm originally from Raleigh, NC.


While much of my research is specifically focused on tensor categories and their applications, more broadly my interests include representation theory, higher categories, topological phases of matter, conformal field theory, subfactors, quantum groups and noncommutative geometry.

My research is supported by NSF Grant DMS-1901082.
