Ingestive Behavior Laboratory
EDUCATIONPhD, Foods and Nutrition, Purdue University, West Lafayette, IN, USA
RESEARCH INTERESTSDr. Apolzan’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 SmartIntake© app. Overall, he conducts translational research in the areas of human clinical nutrition, exercise physiology, and obesity to further reduce disease prevalence.
