I graduated from Cambridge in 1970 with a PhD in mathematics.
After spending two years as an Assistant Professor at Cornell, I moved
to the Department of Combinatorics and Optimization in Waterloo.
In 1992 Chris Godsil, Ian Goulden and I founded the
Journal of Algebraic Combinatorics and stepped down as
managing editors after ten years of service.
I am on the editoral boards of several journals and was, for many
years, a mathematical consultant to the Oxford English Dictionary
I am a Fellow of the Royal Society of Canada
and a Member of the Academy of Mathematical and Physical Sciences.

Research area: algebraic and enumerative combinatorics: application
of these to questions in algebraic geometry, and perturbative quantum field theory.
Current general interest: the use of algebraic and analytic ideas,
together with combinatorial constructions, in questions that have an
enumerative aspect; enumerative questions that arise in algebraic
geometry and mathematical physics.
Current and nascent research projects:
- integrable hierarchies and the Join-Cut Equation;
- using enumerative techniques to find a generalisation of the
Ekedahl-Lando-Shapiro-Vainshtein theorem to the double Hurwitz problem;
- the "b-conjecture": this involves a conjectured invariant of (rooted)
maps (2-cell embeddings of graphs) interpolating naturally between
the moduli spaces of real and complex curves; "b" is associated with
Jack symmetric functions;
- the combinatorics of the beta-Jacobi density function in the context of maps (2-cell embeddings of graphs);
- diagrammatics of 3-manifolds;
- constructive aspects of perturbative quantum field theory, algebraic and combinatorial
aspects of the Legendre and Fourier transforms in this context;
- the study of quantum invariants and Vassiliev invariants of knots as a means of eliciting
properties of Lie algebras and Hopf algebras in the context of enumerative combinatorics.

The following translations from Welsh into English, are work in progress. I hope to find
the time to complete them in the near future.
Chwalfa by T. Rowland Hughes (Gwasg Aberystwyth - 1946).
The word "Chwalfa" has several meanings, including "Destruction", but the one that best
captures one of the powerful themes is `Wilderness'. The novel opens with the wilderness
of a mountainous region, the ultimate significance of which develops slowly though
the novel, and is set during a strike at the slate quarry in a fictional village
called Llechfaen. There are many references to well known politicians and literary figures of
the era. The author has made use of some of the published accounts of certain events associated
with the Great Strike that took place in the Penrhyn Quarry in North Wales in the period
1901 to 1903. The strike was one of the largest experienced in the industrial history
of Britain. The events are seen through the experiences of the extended family of
Edward Ifans, who is a quarryman, and his wife, Martha. The novel gives a vivid
account of cultural and social life in North Wales and in South Wales during these
Y Dylluan Wen by Angharad Jones (Gwasg Gomer, Llandysul, Ceredigion - 2013)
(Enillydd y Fedal Rhyddiaith yn Eisteddfod Genedlaethol Frenhinol Cymru 1995)
While set in the modern era, "The White Owl" opens with a reference to "Gwydion", and
therefore to the "Mabinogi," a collection of stories of great antiquity that are
associated with Wales, and continue to be the subject of scholarly research in Celtic
Studies. They remain, however, less familiar outside Wales. While the novella may at first
appear to be a dark and brooding account of events within a small village, the reader is drawn
gradually towards complexities that demand contemplation, that haunt the imagination and
the intellect, and that have meaning beyond the confines of the village itself.
In an as yet unfinished commentary I have endeavoured to provide sufficient detail from
the Mabinogi, and from other sources (including the Eleusinian Mysteries, and a few of the
techniques of probing the text of the Mabinogi), to reveal enough of the substrate upon
which I believe parts of the novel rest. The commentary is an account of my own reading
and understanding of the novella: others will have their own understanding of it.
