I conduct formative, implementation, and evaluation research to enhance the effectiveness of programs to improve nutritional status and reduce health inequities in the US and globally. My translational work includes qualitative and quantitative research related to maternal and child nutrition; food security, responsive feeding; social support and gender equity; environmental influences on food and physical activity, and capacity building for multisectoral nutrition.  A central focus of my research is the interface between public health nutrition programs and communities, identifying contextual factors that influence motivation, self-efficacy, and capabilities of providers and participants to enhance utilization and effectiveness of interventions for low-income families. 

Implementation research within a large global project to support scale-up of nutrition-specific and nutrition-sensitive interventions for improving nutritional status and well-being of women, children and adolescent girls.

  • Review of effectiveness of social and behavioral change interventions that engage fathers and grandmothers in supporting maternal, infant and young child nutrition in low and middle income countries.
  • Examination of scope and effectiveness of interventions addressing social norms and community-level beliefs to create an enabling environment for individual adoption of recommended practices to improve complementary feeding of young children.

Mixed methods implementation research to build local capacity to address the causes of child stunting in Tanzania. Formative research to develop feasible and effective intervention strategies to build knowledge, skills and motivation to improve infant and young child feeding and dietary diversity, including engagement of fathers in support of improved practices, household food security, and child nutritional status.

Exploratory research on gender dynamics and household decision-making in Tanzania to understand influences on families' ability and motivation to adopt recommended practices to improve maternal and child nutrition.

Evaluation of interventions to prevent unhealthy weight gain among low-income children, delivered through educational programs for parents and community collaborations to promote environmental change.
