The Duke Center on Risk in Science and Society Presents:


COVID-19 Transmission: Estimating Risk in Indoor Settings

Part of the Perspectives on Planetary Risk series

Friday, Nov. 13, 11:00 am – 12:15 pm (Eastern)


Jose Jimenez will review the importance of aerosols for disease transmission, a topic he has been working on with the world’s leading aerosol scientists since March 2020. He will summarize the scientific evidence showing that COVID-19 transmission is driven by aerosols, with a smaller fraction from surface transmission, and with a minor contribution of ballistic “WHO” droplets (only important when coughing and sneezing). Prasad Kasibhatla will discuss how this knowledge of aerosol -driven transmission can be used to derive quantitative estimates of COVID-19 transmission risk in indoor settings using a web-based risk assessment tool (http://covid-exposure-modeler-data-devils.cloud.duke.edu/) he has developed in collaboration with Jose Jimenez and colleagues at Duke. The discussion and audience questions will be moderated by Jonathan Wiener.


Jose-Luis Jimenez is a Professor of Chemistry and a Fellow of CIRES at the University of Colorado at Boulder. He holds a Ph.D. in mechanical engineering from MIT. His research group focuses on advanced real-time aerosol measurements and their application to aircraft and laboratory studies, and on mathematical modeling. He is a Highly Cited Researcher and a Fellow of the American Association for Aerosol Research (AAAR) and the American Geophysical Union (AGU).


Prasad Kasibhatla is a Professor of Environmental Chemistry in the Nicholas School of the Environment (with a secondary appointment in the Civil and Engineering Department in the Pratt School of Engineering) at Duke University. His research focuses on developing a quantitative understanding of the factors that determine the chemical composition of the atmosphere using numerical models in conjunction with surface, airborne, and satellite-based measurements of atmospheric chemical composition.



Jonathan Wiener is the William R. and Thomas L. Perkins Professor of Law, Professor of Environmental Policy, and Professor of Public Policy, at Duke University. He is also the Co-Director of the Duke Center on Risk, in Science and Society, and Past President of the Society for Risk Analysis (SRA).
