Dr. William Winfrey is President at Avenir Health. Dr. Winfrey joined the Avenir Health in 2007 after almost thirteen years at the Futures Group. Dr. Winfrey is the technical lead for developing the Lives Saved Tool (LiST) and the OneHealth tool. He is also the corporate manager for subcontracts with the DHS project and the DELIVER project, as well as the director of business development efforts at the Avenir Health.
At the Futures Group, Dr. Winfrey coordinated working groups for poverty in both the Health Policy Initiative Task Order I and the Measure Evaluation Project. Previous to this he was the director of the Finance and Planning element in the POLICY II Project. Dr. Winfrey was also the director of research within the Center for Private Sector and Communications at the Futures Group.
Dr. Winfrey was one of the leading forces in adapting market segmentation techniques to define the role of the public and private sectors for meeting reproductive health needs of a country’s population. He is an expert in estimating the costs and expenditures associated with delivering health services. He was instrumental in developing WHO’s estimate of global expenditures on TB diagnostics. He has developed country level estimates of family planning services, delivery of services for orphans and vulnerable children and a global estimate of the costs associated with unsafe abortion.
Currently Dr. Winfrey focuses his efforts on the development of the LiST tool and the OneHealth tool. The LiST tool helps health policy and programme managers in developing countries assess the mortality impact of scaling up maternal and child health interventions. The OneHealth tool helps developing country health planners create costed medium term plans that include all costs associated with scale up as well as the mortality impact that would ensue as a result.
Dr. Winfrey is also a health researcher. Among his skills are analysis of survey data sets, estimating costs of health services and development of tools to inform planning of family planning and health efforts. Most recently he has calculated age disaggregated maternal mortality rates, costed family planning methods in Pakistan and Rwanda and designed tools to help local NGOs understand the cost structure of their services.
Dr. Winfrey has bachelor’s degrees in Chemical Engineering and Petroleum Engineering. Following two years of Peace Corps experience in Mali, Dr. Winfrey earned a doctorate in economics from the University of North Carolina at Chapel Hill.
