Research Interests: Pastoralism, Health and Conflict, Humanitarian Response
Regions: Ethiopia, South Sudan

Hannah Wild is an MD Candidate at Stanford University School of Medicine. Her research focuses on the health of nomadic populations and more broadly, the intersection of health, armed conflict, and culture in Sub-Saharan Africa. She received her undergraduate degree in Comparative Literature from Harvard University with special fields in oral literature and ethnography. Prior to beginning medical school she received a post-graduate fellowship to conduct ethnographic fieldwork with the Nyangatom, a tribe of nomadic pastoralists in the Omo Valley of southwest Ethiopia. She spent 18 months living with the Nyangatom’s nomadic cattle camps and studying their traditional medical practices, and is fluent in the local language. She currently leads multi-institution research collaborations to develop methodology for including nomadic groups in population data and household surveys ( Her research on pastoralists' role in regional conflict dynamics was cited by the 2019 United Nations Report of the Commission on Human Rights in South Sudan ( Her work has received support from Stanford’s Center for Innovation in Global Health, Geospatial Center, and Center for African Studies, as well as the American Society for Tropical Medicine & Hygiene and Digital Globe Foundation.

    Urban environments marked by violence create fear that can have real impacts on the urban poor, particularly women and girls. Any efforts to tackle poverty and promote health must address the impacts to their access to livelihoods and education, healthcare, markets, and social support that underlie wellbeing. This study aimed to elucidate specific impacts that violence and fear have on the very poor in rapidly growing cities and the coping strategies employed. This multi-country qualitative study was conducted in Dhaka, Bangladesh, Port-au-Prince, Haiti; and Addis Ababa, Ethiopia. Participants in all three cities employed similar tactics to avoid violence. People adjusted how, when, and where they travel and how they interact with people who threaten them. These coping strategies led participants to spend more money on goods and to restrict access to livelihood opportunities, education, healthcare, and social activities. Women are impacted more than men in all spheres and city specific differences are highlighted. Residents of urban slums, particularly women, in these three cities cope with urban violence in many ways, suffering consequences in a range of categories - leading to significant impacts to their own health and well-being and their families.

  • Making Pastoralists Count: Geospatial Methods for the Health Surveillance of Nomadic Populations. The American journal of tropical medicine and hygiene Wild, H., Glowacki, L., Maples, S., Mejia-Guevara, I., Krystosik, A., Bonds, M. H., Hiruy, A., LaBeaud, A. D., Barry, M. 2019


    Nomadic pastoralists are among the world's hardest-to-reach and least served populations. Pastoralist communities are difficult to capture in household surveys because of factors including their high degree of mobility over remote terrain, fluid domestic arrangements, and cultural barriers. Most surveys use census-based sampling frames which do not accurately capture the demographic and health parameters of nomadic populations. As a result, pastoralists are "invisible" in population data such as the Demographic and Health Surveys (DHS). By combining remote sensing and geospatial analysis, we developed a sampling strategy designed to capture the current distribution of nomadic populations. We then implemented this sampling frame to survey a population of mobile pastoralists in southwest Ethiopia, focusing on maternal and child health (MCH) indicators. Using standardized instruments from DHS questionnaires, we draw comparisons with regional and national data finding disparities with DHS data in core MCH indicators, including vaccination coverage, skilled birth attendance, and nutritional status. Our field validation demonstrates that this method is a logistically feasible alternative to conventional sampling frames and may be used at the population level. Geospatial sampling methods provide cost-affordable and logistically feasible strategies for sampling mobile populations, a crucial first step toward reaching these groups with health services.

  • A Consensus Framework for the Humanitarian Surgical Response to Armed Conflict in 21st Century Warfare. JAMA surgery Wren, S. M., Wild, H. B., Gurney, J., Amirtharajah, M., Brown, Z. W., Bulger, E. M., Burkle, F. M., Elster, E. A., Forrester, J. D., Garber, K., Gosselin, R. A., Groen, R. S., Hsin, G., Joshipura, M., Kushner, A.

    Armed conflict in the 21st century poses new challenges to a humanitarian surgical response, including changing security requirements, access to patients, and communities in need, limited deployable surgical assets, resource constraints, and the requirement to address both traumatic injuries as well as emergency surgical needs of the population. At the same time, recent improvements in trauma care and systems have reduced injury-related mortality. This combination of new challenges and medical capabilities warrants reconsideration of long-standing humanitarian surgery protocols.To describe a consensus framework for surgical care designed to respond to this emerging need.An international group of 35 representatives from humanitarian agencies, US military, and academic trauma programs was invited to the Stanford Humanitarian Surgical Response in Conflict Working Group to engage in a structured process to review extant trauma protocols and make recommendations for revision.The working group's method adapted core elements of a modified Delphi process combined with consensus development conference from August 3 to August 5, 2018.Lessons from civilian and military trauma systems as well as recent battlefield experiences in humanitarian settings were integrated into a tiered continuum of response from point of injury through rehabilitation. The framework addresses the security and medical requirements as well as ethical and legal principles that guide humanitarian action. The consensus framework includes trained, lay first responders; far-forward resuscitation/stabilization centers; rapid damage control surgical access; and definitive care facilities. The system also includes nontrauma surgical care, injury prevention, quality improvement, data collection, and predeployment training requirements.Evidence suggests that modern trauma systems save lives. However, the requirements of providing this standard of care in insecure conflict settings places new burdens on humanitarian systems that must provide both emergency and trauma surgical care. This consensus framework integrates advances in trauma care and surgical systems in response to a changing security environment. It is possible to reduce disparities and improve the standard of care in these settings.
