Theresa Hoke, PhD, MPH, leads multi-disciplinary teams in conducting programmatic research to improve the systems supporting primary health care services in resource-poor settings. She has over 30 years of experience conducting applied research to strengthen public health interventions. She has led teams of investigators examining the feasibility, cost, and value of a community-based integrated development initiative in Kenya. Her implementation research in South Africa, Zimbabwe, Uganda, Tanzania, and Kenya provided evidence to program managers about effective linkages between HIV and family planning services. Another investigation in Madagascar supported the design of a nationally implemented intervention for provision of injectable contraceptives by community health workers. Early in her career, Dr. Hoke provided technical direction for operations research studies testing quality improvement interventions to strengthen child health services. She began her global health career as a Peace Corps nutrition health educator in Niger.
