My research interests include the examination of systems and environmental characteristics that influence nutritional health with an emphasis on the school environment. Currently, I am spear-heading a study to measure the implementation of a school wellness policy. One purpose of this study is to determine the degree to which the policy has been executed. This step is critical before the impact of the policy can be fully assessed. I am also very interested in food insecurity and its impact on nutrition-related behaviors and needs; and attitudes towards obese persons, particularly among health professionals, and the impact of these attitudes on their practice.
