I am an algebraist interested in a vast array of subjects including finite semigroup theory, geometric group theory, algebraic combinatorics, representation theory and automata theory. Another fascinating subject for me is the interconnections between etale groupoids, inverse semigroups and operator algebras. Recently I have been focusing on applications of finite semigroups to the analysis of finite state Markov chains.
