Rebecca Stoltzfus holds a Ph.D.in Human nutrition from Cornell University (1992) and a B.A. in Chemistry from Goshen College (1984). From 1992-2002, she was assistant and then associate professor in the Department of International Health, Johns Hopkins Bloomberg School of Public Health. She joined the Division of Nutritional Sciences in 2002 as an associate professor and was promoted to professor in 2005. For the 2008-09 academic year, she was a visiting professor in the Department of Community Health, Kilimanjaro Christian Medical Center, Moshi Tanzania.
Her research focuses on the causes and consequences of malnutrition in women and children in developing countries. Current major projects include the SHINE (Sanitation, Hygiene, and Infant Nutrition Efficacy) Trial in Zimbabwe, Mycotoxins and Infant Growth (Zimbabwe and Tanzania), Implementation Science for Scaling up Nutrition (Tanzania), and a project in Kenya and Ethiopia to translate the new global recommendation for calcium supplementation in pregnancy into policies and programs in Kenya and Ethiopia.
The goal of my research program is to improve the health and well being of women and children in low-income communities by improving their nutritional status. Current major research projects include:
- Sanitation, hygiene and infant nutrition efficacy (SHINE) Trial: effect on tropical enteropathy, anemia and growth in young children in rural Zimbabwe. A cluster-randomized factorial trial. (in collaboration with ZVITAMBO Project, Harare Zimbabwe, and the Johns Hopkins Bloomberg School of Public Health).
- Maternal capacities for child care: development of an interdisciplinary framework (in collaboration with ZVITAMBO Project, Harare Zimbabwe, and Alive & Thrive Project, Bangladesh)
- Establishing the link between mycotoxin exposure, gut function and stunting in Zimbabwean infants (in collaboration with ZVITAMBO Project, Harare Zimbabwe)
- Implementation Science for Scaline Up Nutrition (Tanzania)

In my teaching, I utilize active learning strategies that foster independent thinking and enable students to integrate concepts from the classroom, their life experiences. In the global health program, we also support experiential learning, in which students can learn through doing. The impact of experiential learning is enhanced by critical reflection, and therefore I embed reflection in all of my courses. As an advisor of graduate students, I support independent thinking and collaboration through an active multidisciplinary research group.
