Dr. Josefa Martinez received her Master of Health Sciences degree from Johns Hopkins Bloomberg School of Public Health and her doctoral degree from Yale University. She is an Associate Research Scientist in the Department of Internal Medicine at the Yale School of Medicine and the Director of the Eastern Caribbean Health Outcomes Research Network (ECHORN) Coordinating Center.
Her research interest is in maternal and child public health nutrition, specifically, how community-based behavior change, health communication, and systems-level interventions can be used to encourage healthy lifestyle behaviors (e.g., breastfeeding) and the effects these interventions have on reducing the risk of overweight and obesity across the life cycle. Her current work and previous experience (at the Yale Center for Emotional Intelligence – formerly the Health, Emotion, & Behavior Lab) focuses on the application of social and behavioral theory to interventions designed to promote healthy lifestyle behaviors. She is also interested in the use of process and summative evaluation approaches to assess the quality and effectiveness of evidence-based public health programming. Her dissertation examined the consequences of excess gestational weight gain and the predictors of exclusive breastfeeding in low-income minority women.
