About me

I am a fourth year PhD student at the University of Glasgow. For the first two years of my PhD I was at Durham University. My supervisor is Dr. Mark Powell. From September 2024 I will be a postdoctoral fellow at the Max Planck Institute for Mathematics in Bonn. My interests are in topology, specifically in knot theory and manifolds, most often in dimensions 3 and 4.

Papers and preprints
