The purpose of my long-term research program is to identify determinants of obesity prevention and body weight regulation across the life span. Using a variety of research designs and settings, these determinants are incorporated into theory-based interventions to lower the burden of obesity. My works focuses primarily on incorporation of optimal food intake and physical activity patterns to promote healthy body weight regulation that prevents chronic diseases, ranging from metabolic syndrome to osteoporosis. Specific aims of ongoing research in my laboratory include testing promotion of healthy choices in meal planning, food preparation and intake of vegetables and fruits in children, adolescents and adults. I serve as the PD/PI or Co-I on several human nutritional sciences studies, including laboratory-oriented clinical trials and community-based interventions with individuals and families.
