Staff Profile

I have been a Professor of Pure Mathematics for School of Mathematics, Statistics & Physics at Newcastle University since 2004, having joined the University in 1991. Since October 2023, my contract is research only. I work mainly on geometrical, combinatorial and computational aspects of group theory. Further details and a list (intended to be complete) of my publications from 1991 onwards can be found on my personal home page.

Roles and Responsibilities

My contract is now for research only, and I have no responsibilities for undergraduate or postgraduate teaching, administration or management at Newcastle University.
