Research Interest
Dr. Dubé's current research interests include 1) the role of lipolysis in skeletal muscle biology, 2) substrate energetics in human health and disease with a special interest in sickle cell disease, and 3) the mechanisms associated with lifestyle interventions (diet and exercise) on tissue metabolism. His research involves cell culture, rodents models, and human clinical studies to address these important topics.
