Reader in 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.
I am the central coordinator for the North British Semigroups and Applications Network (NBSAN), and an editor of the journal Communications in Algebra. The rest of the time I am a father (of three), husband, rambler, fellwalker, consumer, commuter, cyclist, motorist, genealogist, cross-country skier and crossword enthusiast.
- A new research preprint, Convexity of tropical polytopes (joint with Marianne Johnson), is available here.
- An NBSAN meeting was held in St Andrews on 22nd and 23rd April 2015. You can read all about it in Peter Cameron's blog.
- A slightly less new research preprint, A large class of sofic monoids, is available here.
- An even less new research preprint, A strong geometric hyperbolicity property for directed graphs and monoids (joint with Robert Gray), is available here.
