My research is focused on the empowerment-related mechanisms through which community-based interventions redress social and health disparities resulting from the social or physical environment. Specifically, my contributions to research have involved four related areas: (1) development of empowerment theory; (2) development of instruments that assess constructs relevant to empowerment; (3) examination of participatory processes facilitating empowerment; and, (4) investigation of public policies and other environmental conditions that are associated with social and health disparities and which may serve as targets of empowerment-based intervention.
