About me

I am currently the McDuff Postdoctoral Fellow at the Mathematical Sciences Research Institute. From January 2017 I will be a Titchmarsh Research Fellow in the Topology group at the University of Oxford. Previously I spent two years at UCLouvain, and a year at Université Paris-Sud, Orsay. I completed my PhD at the University of Oxford under the supervision of Cornelia Drutu, and wrote a Master's thesis at the University of Birmingham under the supervision of Ralf Köhl.

Research interests

Geometric group theory
Gromov hyperbolic groups and their generalisations
Coarse geometry and embeddings
