Biography

Dr. Marie-Claude Audet is an Assistant Professor in nutrition, stress and mental health in the School of Nutrition Sciences at the University of Ottawa. She also holds an adjunct scientist appointment at the Institute of Mental Health Research (Royal Ottawa Mental Health Centre) and an adjunct professor appointment in the Department of Neuroscience at Carleton University. Before joining the University of Ottawa in 2017, Dr. Audet has a scientist position at the Institute of Mental Health Research (Royal Ottawa Mental Health Centre) where she established a research program on the gut microbiota-immune-brain axis, stress, and mental health. She also completed a postdoctoral fellowship in the Department of Neuroscience at Carleton University during which she examined the contribution of brain inflammatory factors to stress-related disorders (depression, anxiety).

Dr. Audet’s current research aims to understand how early-life and adult stressful experiences may come to promote vulnerability to mental illnesses, with a specific focus on the gut microbiome-immune-brain axis. Her research examines the mechanistic underpinnings by which gut bacteria communicate with the brain under stressful conditions and come to influence mood and behavior. She also investigates the effects of microbiota-targeted interventions (e.g., probiotics, prebiotics) in limiting microbial, inflammatory, and depressive/anxiety effects stemming from stressor exposure. Dr. Audet shares collaborative relationships with researchers and clinicians in both fundamental and clinical disciplines. Her research work is being funded by the National Sciences and Engineering Council of Canada (NSERC Individual Discovery Grant) and the University of Ottawa Medical Research Fund.
