An international specialist in reproductive health, Rachel has conducted clinical, epidemiologic and social research on the successful implementation of health technologies and services in resource-poor countries. An early specialist on the introduction of contraception into poor countries, Snow published widely on the balance of health concerns, social preferences, gendered constraints and service factors affecting the use of reproductive technologies. As the HIV/AIDS epidemic placed growing demands on health services to offer HIV testing and care, Snow's work expanded to explore the behavioral and operational challenges of HIV/AIDS programs in Burkina Faso, Nepal and South Africa. With attention to the biologic and social vulnerabilities of both sexes, she examines the extent and causes of sex differences in the use of HIV care in a range of African countries, and the impact of different service models on access. A reproductive biologist and gender theorist, Snow has also written extensively on the intersection of sex, gender and vulnerability to selected health outcomes. Snow has conducted consultant missions to design and evaluate reproductive health and HIV programs across Africa and Asia, with sustained work on reproductive health programs in Burkina Faso, Nigeria, South Africa, Nepal, India, Bangladesh and China.
Snow has served on numerous expert committees at the World Health Organization, and is currently a member of the Women and Gender Equity Network for the WHO Commission on Social Determinants of Health. Snow was a co-author of the WHO curriculum Transforming Health Systems and a founding editor of the African Journal of Reproductive Health, now published from Nigeria. Snow received her doctorate in Population Sciences from Harvard in 1988, where she was subsequently a MacArthur Fellow in Population and Development Studies, and Assistant Professor of Reproductive Health. From 1997-2002 she served on the Faculty at the University of Heidelberg (Germany), where she was Unit Head for Reproductive Health. Since 2003 she has been based at the University of Michigan.
