About this conference
Dr. St-Onge will discuss their studies demonstrating a bidirectional link between sleep and food intake. Lack of sleep has a direct influence on food intake. In turn, what we eat also influences the quality of our sleep. This can result in either a vicious or virtuous cycle.

About Marie Pierre St-Onge
Dr. St-Onge is the founding director of the Center of Excellence for Sleep and Circadian Rhythm Research at Columbia University Irving Medical Center. The main focus of her research is to study the impact of lifestyle, particularly sleep and diet, on cardiometabolic risk factors. Dr. St-Onge has been funded by the National Institutes of Health (NIH in the United States) since 2008, conducting innovative clinical research combining her expertise in sleep, nutrition, and energy balance regulation to address questions related to the role of circadian rhythms, including sleep duration and timing, as well as meal times and eating habits, in cardiometabolic risk. Dr. St-Onge has been director of the American Heart Association (AHA)-funded Go Red for Women Strategically Focused Research Network, aimed at determining the causality of the relationship between sleep and cardiovascular disease, as well as the specific role that sleep plays in women's health throughout the life cycle.
She is a pioneer in this field, having chaired the first AHA-approved scientific statements on sleep and cardiometabolic health, as well as on meal timing and frequency and the prevention of cardiovascular disease risk. More recently, she chaired a follow-up scientific statement highlighting the role of multidimensional sleep health in cardiometabolic health. She is the recipient of an Outstanding Investigator Award bestowed by the National Institutes of Health and is the author of nearly 200 peer-reviewed publications.
