Dr. Apolzanā€™s research interests involve overseeing and managing human clinical intervention trials examining nutritional, physical activity, and body weight outcomes across the lifespan. He has experience with clinic-based and mHealth interventions. He also has worked extensively with the remote food photograph method (RFPM) and SmartIntakeĀ© app. Overall, he conducts translational research in the areas of human clinical nutrition, exercise physiology, and obesity to further reduce disease prevalence.
