Research Interests

Dr. Engle-Stone's research is in global public health nutrition, with a focus on micronutrient nutrition among women and young children in low-income settings. Research themes include planning, monitoring, and evaluation of food fortification programs; cost-effectiveness and coherence among micronutrient intervention programs, and nutritional assessment.
