Scott Heximer is Associate Professor in the Department of Physiology and has served as Interim Chair since May 2019. He is also a principal investigator for the Ted Rogers Centre for Heart Research, and holds a Canada Research Chair in Cardiovascular Physiology, Tier II. In addition to his CRC, Dr. Heximer has received the Canadian Hypertension Society New Investigator Award, and the American Heart Association and Lucille P. Markey Special Emphasis Pathway in Pathobiology postdoctoral fellowships.

Heximer is President of the Canadian Society for Atherosclerosis Thrombosis and Vascular Biology where he was also Chair of the Organizing Committee for the 2018 International Symposium of Atherosclerosis. He has published more than 55 peer-reviewed publications, including in top-ranked journals such as the Proceedings of the National Academy of Sciences and The Journal of Clinical Investigation, among many others. His work has over 2600 cumulative citations.

Professor Heximer’s research focuses on understanding the signalling pathways and phenotypic variation in cardiac fibroblasts. His work investigates the roles and mechanisms of heterotrimeric G-protein signalling in the cardiovascular system. He was part of the research team that discovered a novel G-protein signalling regulator, RGS2, and created a research program to characterize its role in cardiovascular physiology. To date, his work in pre-clinical models has uncovered the importance of these pathways in the pathogenesis of numerous cardiovascular and respiratory diseases, including hypertension, asthma, atrial fibrillation, and heart failure.
