I obtained a PhD in Environmental Engineering from UPC in 2005. Shortly after, I was appointed Mineral Dust Group Leader at the newly created Barcelona Supercomputing Center (BSC). I then worked in the United States at NOAA/NCEP, IRI at Columbia University, and the NASA Goddard Institute for Space Studies. In 2016, I returned to BSC as Head of the Atmospheric Composition Group, AXA Professor on Sand and Dust Storms, and a Ramon y Cajal Fellow. In 2017, I was awarded the Agustín de Betancourt y Molina Prize by the Spanish Royal Academy of Engineering for my contributions to environmental risks. I also obtained an ERC Consolidator Grant, which began in October 2018. I am a Co-Investigator of NASA's EMIT mission, one of only two Earth Ventures-Instrument missions funded in 2018. In December 2019, I was appointed ICREA Research Professor.

I am focused on understanding atmospheric aerosols and trace gases, from the physical and chemical processes that influence them to their impacts on weather, climate, ocean biogeochemistry, air quality, and human health. My research group works to improve the representation of pollutants in atmospheric and climate models, characterizing their sources, sinks, atmospheric lifecycles, and effects. I am particularly known for my work on dust aerosols. In this area, I hold an AXA Chair, addressing both fundamental and applied research questions related to dust. Additionally, I lead an ERC Consolidator Grant that explores the role of dust's mineralogical composition in its climate effects, combining theory, experimental campaigns, remote spectroscopy, and advanced modeling.
