John Kelton is a physician scientist whose investigation of platelet disorders and the management of these platelet disorders has led to international recognition. His research focussed on a study of platelets (tiny blood cells important for clotting) and diseases of these platelets. His basic studies have been complemented by clinical trials that have changed the management of many patients (for example, pregnant women with platelet disorders) around the world.

Patrick and Edith McGeer's neurological research is recognized worldwide as responsible for many signal advances in the understanding of Alzheimer's disease and Parkinson's disease, and for the important kainic acid model of Huntington's disease. Their groundbreaking hypotheses on neuroinflammation in neurodegenerative diseases and anti-inflammatory therapy are now strongly supported and part of the main focus for research into Alzheimer's disease.

Peter St George-Hyslop is an international leader in research on neurodegenerative diseases. He pioneered the use of genetic approaches to elucidating the basis of these diseases. His research has provided insight into biological mechanisms regulating the disposition of membrane proteins associated with development and aging, and profoundly altered our understanding of neurodegeneration.

Warwick Vincent is a world leader in polar microbial ecology. He has pioneered unique insights into microbial interactions that link the structure and functions of communities at the base of food chains in the Subarctic, Arctic and Antarctica. His research and ability to synthesize studies from different parts of the world are having a major influence in international polar science.

Robert J. Birgeneau is one of Canada's foremost experimental physicists and has made numerous original, and profound contributions to our understanding of condensed matter systems. He is widely known for his pioneering use of neutron and x-ray scattering in elucidating the nature of the phase transitions and excitations in many of the one-, two- or three-dimensional materials that have been and continue to be at the forefront of research in condensed matter and statistical physics.

J. Peter Guthrie is a scientific leader in developing methods for the prediction of rate constants for chemical reactions in solution. He began with studies of the application of Marcus Theory to organic reactions, then developed Multidimensional Marcus Theory to treat concerted reactions in terms of the hypothetical stepwise reactions, and recently developed No Barrier Theory, which allows calculation of the rate constants for a great many reactions in solution with no adjustable parameters.

Niky Kamran, Department of Mathematics and Statistics, McGill University, is a leading researcher in the geometric study of differential equations. In a series of joint papers with Finster, Smoller and S. T. Yau, he has recently established sharp estimates for the long-time behaviour of Dirac fields in axisymmetric black hole geometries. His work on differential invariants and conservation laws for differential equations has led to an in-depth understanding of the property of geometric integrability for hyperbolic equations. He is also a founder of the rapidly expanding field of quasi-exactly solvable spectral problems in quantum mechanics. The growth of this field is due to a significant extent to his foundational papers. He is the recipient of the André Aisenstadt Prize in 1992, and is a Laureate of the Royal Academy of Sciences of Belgium. He won that academy's prize in mathematics in 1988 for his research monograph "Contributions to the study of the equivalence problem of Elie Cartan and its applications to partial and ordinary differential equations."

George A. Sawatzky is recognized as one of the most respected researchers in the field of condensed matter. His pioneering work on the electronic structure of strongly correlated systems, and his contribution to the understanding of physical properties of transition metal oxides and the interplay between the spin, charge and orbital degrees of freedom have made him a much sought-after speaker at international conferences.

Dan Wayner has made seminal contributions to the electrochemistry, kinetics and thermochemistry of organic free radicals and radical ions. His innovative studies provided the first comprehensive compilation of standard potentials of radicals, dramatically increased the store of reliable bond dissociation energies and generated many novel chemical probes of reaction mechanisms.

Heather Munroe-Blum is a scholar and policy leader of international reputation. She is a leading figure in advancing the impact of university-based research in Canada, in championing effective science and innovation policy, as well as the positioning of Canadian higher education, research and researchers in the international context.

Dr. Hans Hofmann is one of the world's leading experts on Precambrian life. He has developed techniques and criteria for distinguishing between biologically and physico-chemically produced structures in very ancient rocks, of potential value in future extra-terrestrial space exploration. His names for the subdivisions for the Precambrian time scale have been accepted by the International Union of Geological Sciences.
