Jean Humphrey, Sc.D.

Professor, Department of International Health, Bloomberg School of Public Health, Johns' Hopkins University

Jean is a public health nutritionist and has been on the faculty of the Johns Hopkins Bloomberg School of Public Health since 1992. She has been based in Harare, Zimbabwe, since 1997, where she directs the Zvitambo Institute for Maternal and Child Health Research. Zvitambo was initially formed to conduct a vitamin A supplementation trial among 14,110 mother-infant pairs; to date this trial has produced more than 50 publications. This productivity is a tribute to the dedicated and highly skilled group of scientists in Zvitambo and close collaborative working relationships with the Ministry of Health and Child Care nurtured and enjoyed over the years. In the September 2009 issue of the Lancet, Jean published the hypothesis that tropical enteropathy (now referred to as environmental enteric dysfunction), caused by poor environmental sanitation and personal hygiene, is a primary underlying cause of poor child growth. She is now the PI of The Sanitation, Hygiene, Infant Nutrition Efficacy (SHINE) Project, designed to test this hypothesis.
