Eric Ravussin, PhD is Associate Executive Director for Clinical Sciences at Pennington Biomedical and a Boyd Professor at Louisiana State University. Dr. Ravussin is an internationally recognized translational investigator in obesity and type 2 diabetes research. Over his more than 35 year career, he has conducted numerous clinical investigations on measures of energy expenditure, body composition, carbohydrate metabolism and biomarkers of aging in health and disease states. Over the past 15 years he has also established a wet lab studying skeletal muscle and adipose tissue cross talks and the relationship of these two tissues on inflammation, nutrient partitioning and insulin sensitivity. His research now focuses on the molecular basis of obesity and its co-morbidities. His studies are aimed at understanding the molecular mechanisms that determine the inter-individual variability in energy expenditure, fat oxidation and energy balance in response to caloric restriction, increased or decreased physical activity, overfeeding or physiological conditions such as puberty, pregnancy or menopause.
