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 13 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 Mathematics 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. From 2009-2014 I was Chair of the International Society of Antique Scale Collectors (Europe). I am a member of the British Numismatic Society. and in 2014 I was Vice-President of the British Society for the History of Mathematics.
