Dominic Welsh awarded an honorary DMath Degree and addressed convocation

Dominic Welsh is a leading contributor to combinatorial mathematics in several ways. In research, his significant contributions began with his doctoral thesis, "On stochastic processes, with special reference to percolation theory". This was a basis for much further work, including the Russo-Seymour-Welsh theorem.

Mike Newman awarded CMS Doctoral Prize

As a graduate student of Professor Christopher Godsil, University of Waterloo, Michael Newman wrote an outstanding dissertation which presents extensions and applications of the Delsarte-Hoffman bound on the size of independent sets in graphs. The thesis interweaves the solutions of three intriguing yet ostensibly unrelated problems into a unified tapestry by virtue of their common methodological treatment. The results obtained are important and the exposition first-rate.

Penny Haxell awarded the 2006 Krieger-Nelson Prize

Professor Penny E. Haxell works in combinatorics and graph theory, focussing on combinatorial, probabilistic and, more recently, topological tools in a very fascinating manner. In all her work she exhibits impressive capability, originality and technical ability, and her pioneering work is well known internationally.

Her work in 1995 with Kohayakawa and Luczak, led to a profound study of Szemeredi's lemma in a sparse setting, and their methods are still being developed fruitfully by others.
