Dr. Leligdowicz completed her medical degree at McGill University and a PhD at Oxford University as a Rhodes Scholar in HIV immunology in West Africa. She completed an internal medicine residency at the University of British Columbia and a critical care medicine fellowship at the University of Toronto. She pursued her interest in immunology and severe infection as a postdoctoral research fellow at University of Toronto and University of California, San Francisco. Her research focuses on characterizing the relationship between immune activation and endothelial injury, with a goal of elucidating mechanisms of tissue injury resulting from severe infection in critically ill patients. Understanding these pathways may lead to novel therapeutic targets for life-threatening infections. Identifying prognostic biomarkers may lead to the development of point-of-care diagnostic tests that risk-stratify critical illness outcome, in both developed and resource-limited settings.
Area of Academic Focus
Translational medicine research, relationship between the immune system and endothelial injury in critical illness and their role in the pathobiology of life-threatening infection
