Dr. Martinez is a maternal-child public health nutrition investigator and implementation scientist with a focus on translating effective interventions into public health policy and practice in disparity populations. She has extensive experience using social and behavioral theory in research design, piloting, implementation and evaluation. Dr. Martinez’s research focuses on how community-based behavior change, health communication, and systems-level interventions can be used to encourage healthy lifestyle behaviors and the effects these interventions have on reducing the risk of overweight and obesity across the life cycle. Her current work aims to improve maternal-child nutrition in the WIC population through breastfeeding protection, promotion, and support. Her current research also examines the role of food security in nutrition-related cardiometabolic outcomes in disparity populations.
