During the last 20+ years, he has supervised and provided technical support to more than 50 studies in developing countries that evaluated interventions for improving neonatal survival, improving access for pregnant women to emergency obstetrical care, treatment and prevention of malaria, HIV/AIDS, micronutrient deficiencies, diarrheal disease, and pneumonia.

Dr. Hamer currently has active projects in Bangladesh, Zambia, South Africa, and the United States. Major current projects include neonatal sepsis prevention using prebiotics and probiotics in Bangladesh; using community health workers to improve early childhood development in rural South Africa, antiretroviral adherence among congenitally infected HIV-positive children in Lusaka, Zambia; and a scaled-up evaluation of community-based mothers’ groups for improving early child development in rural Zambia. In addition, Dr. Hamer is the PI for the GeoSentinel Surveillance Network, a global network of 70 sites in 31 countries that conducts surveillance of emerging infectious diseases using returning travelers, immigrants, and refugees as sentinels of infection (www.istm.org/geosentinel).
