Welcome to my webpages.
This homepage contains links to information about my activities and interests. If you would like to know more, please send me an email.
I was born in 1941, and after studying at Cambridge University, I became a professional mathematician and university teacher in 1963. A brief curriculum vitae is available.
From 1988 to 2006 I was Professor of Mathematics at the London School of Economics, where I was also Director of CDAM, the Centre for Discrete and Applicable Mathematics. I have written 12 books and over 100 papers on mathematical topics, many of them in algebraic combinatorics and its applications. I became Emeritus Professor in 2006 and continue to teach MA318 History of Mathemtics in Finance and Economics for undergraduates.
I am a member of the Editorial Board of the Journal of Algebraic Combinatorics.
I am a former General Secretary and a member of the Council of the London Mathematical Society.
My hobby is writing about the history of weights and scales. I am currently Chair of the International Society of Antique Scale Collectors (Europe), and a member of the British Numismatic Society.
