Melissa Napolitano is a Professor and the Interim Chair of the Department of Prevention and Community Health. She also holds a secondary appointment in the Department of Exercise and Nutrition Sciences. 

Dr. Napolitano uses behavioral science principles and communication techniques to develop, implement and evaluate physical activity and weight management programs for delivery via digital strategies. Her work focuses across the lifespan, including pregnancy and young adulthood. She is interested in the developmental life stage of emerging adulthood and understanding the formation of positive eating and activity behaviors, as well as health-risk behaviors such as disordered eating and tobacco use. She has more than 90 peer reviewed publications and book chapters. Dr. Napolitano’s research has been funded by the National Institutes of Health, the American Heart Association, and the Robert Wood Johnson Foundation. Dr. Napolitano was a Consultant to the 2018 Physical Activity Guidelines Advisory Committee, specifically working with the Physical Activity Promotion Subcommittee. She has served in review and editorial capacities as a standing member of the NIH Psychosocial Risk and Disease Prevention Study Section and Senior Associate Editor of the Journal of Physical Activity and Health. She is a current Fellow of the Society of Behavioral Medicine (SBM) and is SBM’s representative to the Roundtable on Obesity Solutions, National Academies of Sciences, Engineering, and Medicine. Prior to joining GWU in 2012, Dr. Napolitano was on the faculties of Brown Medical School and Temple University at which she was also a research scientist at the Center for Obesity Research and Education.

PROFESSIONAL SERVICE

Dr. Napolitano is a Fellow of the Society of Behavioral Medicine (SBM) and has served in a variety of leadership, review, and editorial capacities. She is SBM’s representative to the Roundtable on Obesity Solutions of the National Academies of Sciences, Engineering, and Medicine. In 2017, she was appointed as a Consultant to the United States Department of Health and Human Services 2018 Physical Activity Guidelines Advisory Committee as a member of the subcommittee on the Physical Activity Promotion. She was a standing member of the NIH Psychosocial Risk and Disease Prevention Study Section from 2015-2019 and Senior Associate Editor of the Journal of Physical Activity and Health from 2016-2020. She is currently an appointed Member of the Strategic Health Initiative on Obesity for the American College of Sports Medicine.

EDUCATIONAL PUBLIC HEALTH PRACTICE

As part of the field learning experience for PubH 6500, Dr. Napolitano and her students work directly with non-profit agencies to address public health topics and areas of need for the clients. The class works in teams on a grant proposal related to one of the top health domains. The projects target a health domain and specifically focus on changing a behavior or social topic (i.e., physical activity, social connection, falls among the elderly). Groups present their program plan to the class and agency; the top two proposals are selected for possible funding submission by the Agency.

Dr. Napolitano's research is focused on delivering evidence based psychosocial interventions for physical activity and weight management through innovative digital delivery channels. Her work specifically addresses physical activity promotion, weight loss, and prevention of weight gain at various life stages including young adulthood and during pregnancy and the postpartum period. Dr. Napolitano's research leverages digital tools and health communication strategies to improve cardiovascular and metabolic health and reduce health disparities. This research has high translation potential and is well-suited for developing multidisciplinary partnerships. 

Her current and recently funded projects include:

Understanding associations between timing of physical activity and health outcomes in young adults

The research component of this predoctoral fellowship training award examines the association of the timing of physical activity and health outcomes, specifically cardiometabolic risk and obesity.
