Dr. Danielle (Dani) Poole is a population health scientist notable for her contributions to the evidence base for humanitarian decision-making. Within the broader field of humanitarian health research, her work is centered around two themes: 1) measuring needs among populations affected by crises with a focus on health during displacement, and 2) developing novel research methods for complex settings. To address these lines of inquiry, Dr. Poole applies methodological approaches spanning the epidemiological, geospatial, and biostatistical sciences. Recent and ongoing research contributions that have informed humanitarian response include the Yale University independent review of the Joint Intersectoral Analysis Framework (in partnership with UNOCHA), development of the Humanitarian Data Strategy for UNFPA’s Humanitarian Office, and geospatial analysis of health facility attacks in Ukraine and the Gaza Strip. Findings from her work have been featured at numerous conferences, including meetings of the National Academy of Sciences, as well as peer-reviewed and popular media publications. Dr. Poole completed a postdoctoral research fellowship at the Neukom Institute for Computational Science of Dartmouth College. She earned a ScD from the Harvard Chan School of Public Health, an MPH from Brown University, and a BA from Seattle University.
