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). For more information see the Child Diet and Health Disparities Lab.


Dr. Gallo has taught classes in Lifespan Nutrition, Nutritional Assessment, and Research Methods. She currently teaches Micronutrient Nutrition (FDNS 4100/6100) and Food and Nutrition Policy (FDNS 4600/6600E).

Current Research

  • Optimal Vitamin D for Maternal and Infant Health: This work explores adherence with current infant vitamin D policies and requirements.  We are also exploring predictors and health outcomes associated with maternal vitamin D status.
  • "What Children Eat" Studying Children's Diet Recall Accuracy: This work focuses on improving the accuracy of dietary recalls among elementary school-aged children, through exploring the effects of age, body mass index, and race/ethnicity. 
  • Improving Access to Prenatal/Postpartum Nutrition: Receiving proper nutrition before, during and after pregnancy can improve both mother and offspring health. We are gathering information into the gaps in prenatal nutrition education as well lactation support in rural Georgia which will inform future community intervention/s.
