About Me
I am a Research Associate at Durham University working in the group of Jack Shotton. Previously, I was a postdoc at the University of Sheffield mentored by Robert Kurinczuk. Even before that I was a PhD student at Imperial College London and the London School of Geometry and Number Theory supervised by David Helm.
