My primary academic interests include the design and implementation of randomized controlled trials and observational studies of maternal, neonatal and child health, and infectious diseases, with emphasis on nutritional factors. About eight million children under age five die each year, with approximately 40% of child deaths occurring during the neonatal period. Malnutrition is the underlying contributing factor in over one third of all child deaths. The majority of under-five child deaths are due to diseases that are preventable and treatable through simple, affordable interventions. Many of these deaths are caused by poor maternal and fetal conditions during or even prior to pregnancy, such as infections or poor nutrition. Our research is focused on addressing global health issues in populations in Tanzania, Uganda, India, Brazil, and other developing countries. Our efforts include a significant component of building research capacity and training at partner institutions.
Maternal and Child Health
We examine the inter-relationships of nutrition, adverse pregnancy outcomes, and maternal and child health. We have completed several clinical trials (and others are ongoing) to examine the efficacy of specific micronutrient interventions provided to pregnant women and/or children. We are also pursuing efforts to address the problems of maternal and neonatal mortality by providing an integrated set of interventions to strengthen health systems and bridge the gaps between health facilities and the community.
We address the interactions of nutrition with immune function, and disease occurrence and severity. Using observational and intervention study designs we examine the role of micronutrient status, other aspects of nutritional status (anthropometric, breast feeding, dietary intake), antiretroviral drugs on the rate of HIV disease progression among adults and children, and the risk of mother-to-child transmission of HIV-1. We also examine the interactions of nutrition and TB (among HIV infected or uninfected patients), malaria (in pregnancy and among children), and common childhood infections.
