I am a student at the Australian National University. I am working on a PhD in mathematics under the supervision of Scott Morrison. My research is in category theory and operator algebras. In particular I work with fusion categories, subfactors, and algebras constructed from topological groupoids. My thesis involves classifying pivotal fusion categories generated by objects of small dimension. This research is kindly supported by the Deakin PhD Scholarship and an ANU Supplementary Scholarship.
