Maternal and infant nutrition is related to child growth and later health as an adult. Hence, Dr. Gallo's research focuses on nutrition during the critical periods of development, from pregnancy to childhood. She has conducted seminal work on infant vitamin D requirements and continues to explore adherence and the appropriateness of current vitamin D recommendations for bone development. She is also interested in the diets of young children and how these relate to healthy growth. She works with vulnerable populations including those participating in the Supplemental Nutrition Assistance Program for Women, Infants and Children (WIC). Her most recent work includes the development of culturally adapted interventions for pediatric obesity management among Latinos.


Dr. Gallo has taught courses in Micronutrients, Nutrition Across the Lifespan, Nutritional Assessment and Nutrition Research Methods.

Current Research

  • Infant Vitamin D: Breast fed infants are susceptible to vitamin D deficiency because breast milk contains insufficient amounts. Hence, public health guidelines suggest infant vitamin D supplementation to begin at birth yet, only 1/3 of US infants meet this recommendation. Dr. Gallo's most recent work in this area explores adherence with current infant vitamin D policies and requirements among low-income and racially/ethnically diverse populations.
  • Vidas Activas y Familias Saludables (VALÉ): Latino children have an almost 3-fold higher risk of obesity, compared to their white counterparts. They also have less access to treatment programs. With colleagues in exercise and psychology, Dr. Gallo has developed a culturally-adapted pediatric weight management program in Latino communities. She is currently testing the effectiveness of family-based, group treatment among low-income Latino children who are overweight or obese.
  • What Children Eat: Errors in dietary assessment limit the ability to assess to detect true diet- diseases associations. Children are unique in dietary assessment due to developmental and cognitive immaturity.  Dr. Gallo's work focuses on improving the accuracy of dietary recalls among elementary school-aged children, through exploring age, body mass index and race/ethnicity.
