Dr. Sina Gallo, RD, PhD, is an Assistant Professor in the Department of Nutrition and Food Studies where she teaches courses in nutrition research methods, micronutrients and lifespan nutrition.  She is a clinician-scientist trained as a Registered Dietitian with a research background in child health. She uses dual-energy X-ray absorptiometry (DXA) for the assessment of bone health and lean body mass, and is skilled in dietary assessment methods and coordination of clinical trials.  She has been published in well-recognized nutrition and medical journals, presented at national and international conferences, and has received awards for her work. She is an active member of the Academy of Nutrition and Dietetics, serves on the Malnutrition in Pregnancy Evidence Analysis Project and member of the Virginia WIC Medical Advisory Committee.  She is affiliated with Inova Health Systems and George Mason Center for Sports Performance.  Her current research explores the role of early life nutrition in chronic disease prevention.  She works primarily with ethnic minority populations and in the development of culturally adapted behavioral health interventions for pediatric obesity management.  Current research interests also include adherence and adequacy of maternal and infant vitamin D supplementation and possible benefits to bone health.
