Ellie Graeden, PhD is a Research Professor with the Georgetown University Center for Global Health Science and Security. Dr. Graeden spent the last decade establishing and leading a private company, Talus Analytics, in designing and building data products to solve challenging problems at the intersection of policy, science, and strategy. She now leads the health intelligence research pillar at the Center, including a team of data scientists, where she uses data architecture and engineering to address challenges in global data sharing for health response and investment. Dr. Graeden has extensive experience developing quantitative approaches for global-scale decision making. With an emphasis on applying the best available data to policy and response decisions, she has led projects in support of Federal and state governments to coordinate data-driven decision making for public health emergencies and other hazards, including extensive work during COVID-19 in local, state, national, and international response efforts. Her work helping lead the analysis of policy and investments in global health security were presented at the United Nations Biological Weapons Convention Meeting of Experts and used to inform costing estimates for the Global Fund and the G20. She and her team have designed and developed data systems to collect and analyze policy data for HIV and COVID-19 and to support visibility into health care capacity for CDC, including hospital operations, caseload, and vaccination data for influenza and COVID-19. She is now expanding this work to evaluate the policy environment for data sharing in these contexts and beyond, with a specific focus on data privacy policy and the data engineering systems to implement those policies. Dr. Graeden earned her undergraduate degree in microbiology from Oregon State University and her doctorate in biology from the Massachusetts Institute of Technology (MIT).
