Through the development and exploitation of new experimental techniques, he has made seminal contributions to the study of the electroweak interaction, proton structure and heavy quark physics. Through his leadership, a team of 100 Canadian scientists is playing a significant role in the ATLAS experiment at the CERN Large Hadron Collider, a project designed to uncover the fundamental mechanism for mass and search for phenomena that would allow us to understand the properties of the basic forces.

The role of lymphocytes in immunity is one of the most actively investigated topics in biomedical research. One of the leaders in the field is Dennis Osmond. Not only did he discover the major role of the bone marrow in lymphocyte production, but he contributed to showing that marrow lymphocytes are of the B type. Each one of the B cells carries immunoglobulin receptors capable of recognizing an antigen and, on contact with this antigen, to start proliferating, producing antibodies and releasing them to the circulation. Dennis Osmond has played a major role in defining the contribution of the bone marrow to the immune system. He he has described the rapid renewal of B lymphocytes in bone marrow, the stages through which B lymphocytes must pass in their development and factors controlling these processes. Recently, he has examined the quailty control of B cells in bone marrow and problems that may lead to immunodeficiencies or B cell cancers (Leukemia/Lymphoma).

À la tête d’équipes internationales et pluridisciplinaires, il s’attache à développer des modèles internormatifs rompant avec la logique coloniale.

Long Citation Sarah Otto is the foremost theoretical evolutionary biologist in Canada and one of the most respected in the world. Her research on the evolutionary forces that act on the structure of the genome has revealed novel and surprising insight into such fundamental aspects of an organism as the number of chromosomes present, sex and recombination rates along these chromosomes, and the nature of interactions among genes. Her research has demonstrated how these evolutionary forces depend on aspects of a species and its environment, helping to explain the remarkable diversity of life at the genomic level.

Le professeur Yves Ouellette, professeur titulaire à la Faculté de droit de l'Université de Montréal et ancien doyen de cette faculté est un auteur et un professeur réputé, spécialiste du droit administratif. Cette discipline, qui n'apparaissait pas au programme des facultés de droit du Québec il y a trente ans, y constitue maintenant une matière de première importance. C'est à nos collègues le professeur Gilles Pépin à Montréal, le professeur Dussault à Laval et le professeur Ouellette que le droit québécois doit cet enrichissement tant en doctrine qu'en pratique au Québec. Les recommandations du rapport 'Ouellette' sur les tribunaux administratifs sont retenues par le Gouvernement. Les tribunaux administratifs et le monde juridique profiteront de l'oeuvre du professeur Ouellette.

OVERALL, Christopher - Department of Oral Biological & Medical Sciences, The University of British Columbia Professor Christopher Overall was appointed a Tier 1 Canada Research Chair in Protease Proteomics and Systems Biology (2001-2022) and a Senior Fellow of the Freiburg Institute of Advanced Studies, Albert-Ludwigs Universität Freiburg, Germany (2010–2013), where he is now an Honorary Professor (2014–). He was inducted as a fellow into the Royal Society of Canada, Academy of Science in 2018. He is best known for his development of proteomic methodology for the discovery of protease substrates in vivo, thereby establishing the field of degradomics. He has used these techniques to reveal new biological roles for proteases in immunity and disease, most recently in the COVID-19 pandemic by SARS-CoV-2 proteases, as well as two new molecular correctors to cure MALT1 protease deficiency in a primary immunodeficiency. By generating clinically relevant insights into how proteases dampen disease-fighting defense systems involved in inflammation and immunodeficiency, degradomics has revealed an unexplored layer of complexity in the hierarchy of cell and immune regulation, greatly adding to our understanding of protease function and drug targeting. Dr. Overall completed his B.D.S., Honours Science and Master’s degrees at the University of Adelaide, South Australia; his Ph.D. in Biochemistry at the University of Toronto, Canada; and was an MRC Centennial Fellow in his postdoctoral training with Dr. Michael Smith, Nobel Laureate, Biotechnology Laboratory, UBC.
