RESEARCH INTERESTS

Dr. Apolzan is a nutrition scientist whose research interests involve overseeing and managing human clinical intervention trials examining nutritional, physical activity, and body weight outcomes across the lifespan. He has significant experience in the development and oversight of clinic-based and mHealth interventions. He is the co-inventor of the FoodImage app. Overall, he conducts translational research in the areas of human clinical nutrition, exercise physiology, and obesity to further reduce disease prevalence.
