Professor of Pure Mathematics, School of Mathematics
My mathematical focus is the category of modules over a ring, and similar categories. Usually these are far too complicated to understand in their entirety so we concentrate on the more interesting parts. We also look for associated structures, which might be algebraic, logical, topological or geometric, that organise some of the information in the category and which reflect the complexity of the category. So this is a mixture of algebra, model theory, category theory, .... The interaction between these various parts of mathematics is, for me, an important part of the fun.
My interest in algebra and model theory formed while I was an undergraduate at the University of Aberdeen. Given these interests, Leeds was a natural choice for where to go to work for a PhD. After a couple of years lecturing at Leeds, a Science Research Council fellowship at Bedford College (London) and three years lecturing in the USA (2 years at Northern Illinois University, 1 year at Yale), I returned to spend three years as a University Research Fellow at the University of Liverpool and finally ended up here.
For my research and teaching see other parts of this, and my own webpage. My main public engagement activity was involvement with the Greater Manchester Mathematics Challenge over the thirteen years of its existence. My main "service" activities, apart from the usual refereeing, reviewing, writing of references, have been ten years as an editorial adviser for the journals of the London Mathematical Society (LMS) and being LMS regional organiser for the North of England.
