Research Focus
The goal of my research program to improve the health and well being of women and children in resource-poor environments by improving their nutritional status. Current major research projects include:
- Helminth infections and growth, appetite, and anemia in children under 2 years, and elucidating potential immunological mechanisms that might mediate those effects (in collaboration with the Ministry of Health of Zanzibar, Johns Hopkins Bloomberg School of Public Health, and the London School of Hygiene and Tropical Medicine)
- A clinic-randomized trial of intervention packages to prevent severe pregnancy anemia and its consequences pregnancy in Zanzibari women (in collaboration with the Ministry of Health of Zanzibar, and the Johns Hopkins Bloomberg School of Public Health)
- Development and evaluation of strategies to support infant feeding for babies of HIV-infected mothers in Haiti (in collaboration with GHESKIO Centers) and in Zimbabwe (in collaboration with ZVITAMBO and the Ministry of Health of Zimbabwe).
- Maternal and infant acceptability of a fortified processed complementary food in Zanzibar (in collaboration with the Ministry of Health of Zanzibar).
- Iron status, anemia, and HIV infection in Zimbabwean mothers and babies (in collaboration with the ZVITAMBO Project of the Johns Hopkins Bloomberg School of Public Health).
- Mainstreaming Nutrition Initiative (in collaboration with the International Centre for Diarrheoal Disease Research, Bangladesh).
