I conduct translational formative, implementation, and evaluation research to enhance the effectiveness of community-based programs aimed at improving nutritional status and reducing health inequities in the US and globally. My work includes qualitative and quantitative research related to maternal and child nutrition; food security; micronutrients; responsive feeding; social support and gender equity; environmental influences on food and physical activity, capacity building for multisectoral nutrition, and community engagement.  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 in multiple low-income countries.

Mixed methods implementation research to build local government capacity to address the myriad causes of child stunting, in five regions of 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.

Participatory engagement of local advisors in an innovative mentoring approach to strengthen capacity to deliver intersectoral nutrition programs at the community level. Assessment of the impact of mentoring and other support on nutrition knowledge, self-efficacy and capacity of Tanzanian government cadres in sectors relevant to nutrition to engage in collaboration and planning of multisectoral nutrition actions.

Process evaluation of factors influencing program implementation by Community Health Workers and how the household context, including family support and gender equity, may influence uptake of recommendations for improving infant and young child feeding.

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.

Identification of successful parental child feeding strategies in the context of food insecurity and psychosocial, economic, health, and environmental barriers to adopting practices that support maintenance of healthy child weights.

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.
