Dr. Matt Biggerstaff is an epidemiologist with the U.S. Centers for Disease Control and Prevention where he leads CDC’s influenza forecasting and modeling. In this role, he works to understand and evaluate how forecasting and mathematical modeling can complement influenza surveillance and inform seasonal and pandemic influenza public health actions, including communication and influenza vaccination and treatment. Dr. Biggerstaff also works to develop methods to assess the severity of influenza seasons and pandemics and leads studies to estimate the health and economic impact of influenza and influenza vaccinations.

Jennifer Nuzzo, DrPH, SM, is a Senior Scholar at the Johns Hopkins Center for Health Security, an Associate Professor in the Department of Environmental Health and Engineering and the Department of Epidemiology at the Johns Hopkins Bloomberg School of Public Health, and a Senior Fellow for Global Health at the Council on Foreign Relations. An epidemiologist by training, her work focuses on global health security, with a focus on pandemic preparedness, outbreak detection and response, health systems as they relate to global health security, biosurveillance, and infectious disease diagnostics. She directs the Outbreak Observatory, which conducts, in partnership with front-line public health practitioners, operational research to improve outbreak preparedness and response. Dr. Nuzzo is also the lead epidemiologist for the Johns Hopkins COVID-19 Testing Insights Initiative housed within the Johns Hopkins Coronavirus Resource Center. Together with colleagues from the Nuclear Threat Initiative and the Economist Intelligence Unit, Dr. Nuzzo co-leads the development of the first-ever Global Health Security Index, which benchmarks 195 countries’ public health and healthcare capacities and capabilities, their commitment to international norms and global health security financing, and socioeconomic, political, and environmental risk environments.


Dr. Caitlin Rivers is a Senior Scholar at the Johns Hopkins Center for Health Security and an Assistant Professor in the Department of Environmental Health and Engineering at the Johns Hopkins Bloomberg School of Public Health. Her research focuses on improving public health preparedness and response, particularly by improving capabilities for “outbreak science” and infectious disease modeling to support public health decision making. She is the lead author on the report Public Health Principles for a Phased Reopening During COVID-19: Guidance for Governors which is being used by, the National Governors Association, the state of Maryland, and the District of Columbia to guide reopening plans. Prior to joining the Center for Health Security in 2017, Dr. Rivers worked as an epidemiologist for the United States Army Public Health Center as a Department of Defense SMART Scholar. She also participated in a National Science and Technology Council’s Pandemic Prediction and Forecasting Science and Technology working group. Dr. Rivers serves as an Associate Editor of the journal Health Security.


Dr. Jeffrey Shaman is a Professor in the Department of Environmental Health Sciences and Director of the Climate and Health Program at the Columbia University Mailman School of Public Health. He studies the survival, transmission and ecology of infectious agents, including the effects of meteorological and hydrological conditions on these processes. Work-to-date has primarily focused on mosquito-borne and respiratory pathogens. He uses mathematical and statistical models to describe, understand, and forecast the transmission dynamics of these disease systems, and to investigate the broader effects of climate and weather on human health.
