My interests are in Functional Analysis, especially commutative, semisimple Banach algebras. In particular I work on regularity conditions, rational and polynomial approximation, and the classification of the endomorphisms, homomorphisms and derivations of certain classes of Banach algebras.

Many of the projects available for research students are listed on our Algebra and Analysis research group projects page.

Here is a picture of me with an appropriate sculpture next to the Science library of Brown University, Providence, Rhode Island, during my sabbatical visit, January to July 1999.

Currently I am the Admissions Tutor for the Single Honours Mathematics courses G100 and G103 at the University of Nottingham, and I am also the School Outreach Officer, with responsibility for the School Open Days, Summer Schools, and other outreach activities.

During my lecturing career I have given a wide range of lecture courses/modules at both undergraduate and masters level.
I have taught honours mathematics modules and service teaching modules to students from many disciplines, including Foundation Year Engineering students.
The subjects I have taught include calculus, analysis (real, complex and functional analysis), linear algebra, numerical analysis and graph theory.
I have supervised many final-year BSc/MSc/MMath projects
. Five of these project students (so far) have gone on to become my research students.

In December 2008 I started a new blog on Explaining mathematics (How to explain mathematical concepts in a way that students can understand). As well as discussion of my recent experiences, ideas, and teaching methodology, my blog includes links to a number of my teaching resources, and, in particular, to videos of many of my classes.

My current teaching timetable is available online here.



I am a former British champion of the boardgame Othello®. (I won the title six times between 1989 and 1997.)

Back in 1993 I wrote a program to solve the 6x6 version of Othello. I wrote this up as a fictional report, Amenor wins world 6x6 Championships! in the 1993 newsletter of the British Othello Federation. You can find the relevant issue (FORTY BILLION NODES UNDER THE TREE, JULY 1993) on the page

Here is a poster with some information about Othello: click on the image to see the full size version!
