My interest in the natural world started with a keen interest in collecting insects as a child. This eventually led to my completing my B.Sc. at Queens. After receiving my Ph.D. in genetics at Cambridge University, I took up a Rutherford Fellowship at the University of Sydney. I returned to Canada in 1976, accepting a position at the University of Windsor where I was a professor in Biological Sciences and Director of the Great Lakes Institute. I moved to the University of Guelph in 1990 as Chair of the Department of Zoology. I have served as a member and chair of the NSERC Ecology and Evolution Grant selection Committee. I am a Fellow of the Royal Society of Canada, and hold a Canada Research Chair in Molecular Biodiversity.

The Barcode of Life

We are working towards the development of a DNA barcoding system which uses a small DNA fragment to discriminate species. This work not only promises a simple solution to taxonomic identity, but will generate important new insights into the age of species and their phylogenetic affinities.

Phylogeographic Patterns in Arctic Marine Life

We are carrying out the first studies which are examining the extent and patterning of genetic diversity among key species of zooplankton and benthos from arctic marine waters. This work seeks to ascertain the extent of past population fragmentation in arctic life.

The Evolution of Breeding Systems

We are carrying out work on breeding system evolution with a special emphasis on transitions to parthenogenesis in freshwater crustaceans. Our work is examining both the forces promoting transitions to asexuality and the fate of asexuals.

The Modulation of Genome Sizes

The genome sizes of organisms show extraordinary diversity both among species and within the bodies of single individuals. Our work is examining the origins and implications of this diversity.

The Pattern and Pace of Evolution

The diversification of life is the heart of the evolutionary process. Our work is examining a number of systems to gain a better sense of the rates and nature of character state evolution.

Crustacean Biodiversity

We are employing a variety of genetic approaches to clarify the taxonomic diversity and phylogenetic affinities of freshwater crustaceans. We are also active in creating CD-ROMs to disseminate this information.

Phylogeography of Freshwater Invertebrates

We are carrying out work which is examining the phylogeography of freshwater invertebrates. This work examines both recent invaders and species whose distributions were established in deep time.
