Jose-Luis Jimenez

About

Jose-Luis Jimenez is a Distinguished Professor at the University of Colorado Boulder and an Institute Fellow at the Cooperative Institute for Research in Environmental Sciences (CIRES). His research centers on the development and application of advanced instrumentation for real-time, quantitative measurements of the size, chemical composition, and morphology of submicron aerosols. His work is motivated by the importance of atmospheric aerosols in affecting radiation balance (climate forcing), human health, visibility, and acid deposition, with most effects not well understood due to limitations in instrumentation. Jimenez's group also investigates the role of aerosols in the transmission of respiratory diseases such as COVID-19. His extensive contributions to atmospheric chemistry and aerosol science have earned him numerous awards and honors, including being ranked as a top scientist in environmental science, highly cited researcher, and fellow of major scientific societies. He holds a Ph.D. from MIT and has postdoctoral experience at Aerodyne Research, MIT, and Caltech.

• Airborne transmission of respiratory viruses

  Science · 2021 · 1530 citations

  The COVID-19 pandemic has revealed critical knowledge gaps in our understanding of and a need to update the traditional view of transmission pathways for respiratory viruses. The long-standing definitions of droplet and airborne transmission do not account for the mechanisms by which virus-laden respiratory droplets and aerosols travel through the air and lead to infection. In this Review, we discuss current evidence regarding the transmission of respiratory viruses by aerosols-how they are gene…

  SCHO), identified through global-scale airborne observations that demonstrate it to be a major reservoir of marine sulfur. Observationally constrained model results show that more than 30% of oceanic DMS emitted to the atmosphere forms HPMTF. Coincident particle measurements suggest a strong link between HPMTF concentration and new particle formation and growth. Analyses of these observations show that HPMTF chemistry must be included in atmospheric models to improve representation of key linkag…

The findings of the study, which have been further endorsed by 184 organizations globally, include points of unanimous agreement, as well as six recommendations with >5% disagreement, that provide health and social policy actions to address inadequacies in the pandemic response and help to bring this public health threat to an end.
