Professor and Head of Pure Mathematics
School of Mathematics, University of Manchester
I am a mathematician and computer scientist, interested in semigroup theory, tropical algebra and geometry, combinatorial and geometric group theory, formal languages and automata, cryptography, computational complexity, parallel processing, quantum computing, and especially the interactions between these fields.
When I'm not actually doing maths, I am running the Pure Mathematics Group in Manchester, coordinating the North British Semigroups and Applications Network (NBSAN), or editing the journal Communications in Algebra. And when I'm not doing that, I'm a father (of three), husband, cyclist, rambler, fellwalker, school governor, consumer, commuter, motorist, genealogist, cross-country skier and crossword enthusiast.
