Dr. Mayol-Bracero is an atmospheric scientist, lead of the Aerosol Observing Systems (AOS) group in the Environmental & Climate Sciences Department at the Brookhaven National Laboratory. Dr. Mayol-Bracero research interests are in the temporal and spatial variability of atmospheric aerosols; the characterization of African dust, biomass burning, marine, urban, biogenic aerosols with particular interest in tropical regions; size-resolved aerosols composition and sources; carbonaceous aerosols (organic and black carbon); aerosols-clouds-precipitation interactions; and air quality. She has vast experience leading aerosol field projects and managing field atmospheric stations.  She has participated in a long list of field campaigns that involved ground and airborne deployments including locations as remote as the Maldives, the Amazon Basin, and the Caribbean region.  Dr. Mayol-Bracero is as a member of the International Commission on Atmospheric Chemistry and Global Pollution (iCACGP), the World Meteorological Organization’s Scientific Advisory Group on Aerosols, and the Americas Working Group of the International Global Atmospheric Chemistry (IGAC) project.
