Michelle Bendeck is a Professor in the Department of Laboratory Medicine and Pathobiology at the University of Toronto, and a Scientist in the Translational Biology and Engineering Program at the Ted Rogers Centre for Heart Research. She obtained her B.Sc (Hons) in Physiology at the University of Western Ontario, and her Ph.D. in Cellular and Experimental Pathology at the University of Toronto. She completed postdoctoral research at the University of Washington in the Department of Pathology.
Professor Bendeck is recognized for her pioneering work on matrix biology in cardiovascular disease. Her research is focused on understanding the molecular mechanisms involved in atherosclerosis, pulmonary hypertension, and heart failure. Her research is published in top journals, and she is frequently invited to lecture around the world.
Professor Bendeck has held leadership positions including Vice-Chair of Research in her department for several years, and was elected president of the two major scientific societies, the North American Vascular Biology Organization and the Canadian Society of Atherosclerosis, Thrombosis and Vascular Biology. She was a Heart and Stroke Foundation of Canada Career Investigator, and has held research funding from the Canadian Institutes of Health Research, the National Institutes of Health (USA), the Heart and Stroke Foundation of Canada, the Natural Sciences and Engineering Research Council, and the Canada Foundation for Innovation.
I run a cardiovascular biology lab investigating molecular and cellular mechanisms of atherosclerosis and fibrotic heart disease.
My lab and offices are located in the beautiful new MaRS West Tower. My lab is part of the Translational Biology and Engineering Program (TBEP) in the Ted Rogers Centre for Heart Research.
We have state-of-the-art research space and equipment, all designed to support the needs of our cardiovascular group.
The group is composed of 10 highly collaborative labs equally representing the faculties of medicine and engineering.
Cardiovascular diseases cause the majority of deaths in North America, and represent the greatest cost to the Canadian Health Care system.
We investigate the basic science mechanisms involved in atherosclerosis and heart failure, concentrating on interactions between cells and the extracellular matrix during fibrosis.
We are investigating experimental models of arterial injury and atherosclerosis in transgenic mice, studying the role of extracellular matrix, the novel collagen binding discoidin-domain receptors (DDRs), and cadherins in mediating smooth muscle cell and macrophage responses.
We are particularly interested in the initiation of atherosclerosis, and the atherosclerotic complications of plaque rupture and calcification.
These in vivo experiments are paralleled by in vitro studies investigating the activation of signaling pathways downstream of these receptors.
