I'm Graham Campbell, a second year PhD student of Pure Mathematics at Newcastle University. Previous to this, I was at the University of York working on an research internship, and before that, I was completing my BSc Computer Science and Mathematics.
I am working on problems in algebra and theoretical computer science. In particular, I am interested in geometric group theory and word problems, graph and hypergraph transformation, formal languages and automata, string rewriting, and decision problems. I also maintain various open source packages and am a member of the Laravel framework organisation.
