Dr. Marie-Claude Audet is an Assistant Professor in the School of Nutrition Sciences at the University of Ottawa. She also holds a cross-appointment in the Department of Cellular and Molecular Medicine (University of Ottawa) and adjunct appointments at the Institute of Mental Health Research (Royal Ottawa Mental Health Centre) and the Department of Neuroscience at Carleton University. Before joining the University of Ottawa in 2017, Dr. Audet held a Scientist position at the Royal’s Institute of Mental Health Research 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 and nutritional interventions in limiting microbial, inflammatory, and depressive/anxiety effects stemming from stressor exposure. A major focus of her work is also on the establishment of sex differences in relation to the microbial, inflammatory and behavioral effects of stressors. Her research is being funded by grants from NSERC and UMRF and she is a recipient of the New Frontiers in Research Fund.
