Dr. Stewart's research is related to maternal and child nutrition in low income communities, primarily in developing country settings. Her focus is on both the immediate and long-term effects of poor nutrition during pregnancy and early childhood on birth outcomes, infant and child survival, child growth, and risk of chronic disease in later life.
Dr. Stewart is the interim director of the Program in International and Community Nutrition and the director of the Designated Emphasis.
