Christine P. Stewart, Ph.D.

  • Corinne L. Rustici Endowed Chair in Applied Human Nutrition
  • Professor
  • Nutritionist in AES
  • Faculty member associated with the Master of Advanced Study in Maternal and Child Nutrition Program
Dr. Stewart’s research focuses on the design and evaluation of nutrition and health interventions for women and young children in low income communities. She examines the effects of these interventions on growth, health, and development throughout the life course. She utilizes primarily community-based randomized controlled trials, longitudinal studies, and meta-analyses to synthesize evidence to inform improvements in programs or policy. She collaborates extensively with multi-disciplinary and multi-national teams and has had recent projects in Kenya, Malawi, Madagascar, Bangladesh, and Ecuador.
