I am currently a Titchmarsh Research Fellow in the Topology group at the University of Oxford, a Junior Research Fellow at St Cross College and an Enterprise Fellow of the Mathematical, Physical and Life Sciences Division.
Previously, I spent two years at UCLouvain working with Pierre-Emmanuel Caprace, a year at Université Paris-Sud, Orsay working with Romain Tessera, and was the (first) McDuff Postdoctoral Fellow at the Mathematical Sciences Research Institute for the Fall 2016 semester.
I am currently teaching undergraduate classes at St. Anne's College.
