Biography
Dr. Martinez is an Associate Research Scientist in the Section of General Internal Medicine at the Yale School of Medicine, core faculty at the Equity Research and Innovation Center, and Lecturer in the Department of Chronic Disease Epidemiology at the Yale School of Public Health. 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.
