My research career has principally revolved around the scientific underpinnings for trace elements in the ocean. I am currently a senior scientist leading the Marine Chemistry lab at the Institute of Marine Science of Andalusia (ICMAN) of the Spanish Research Council (CSIC) in Spain. For 20 years, my scientific efforts focus on the role of trace elements (mainly metals and inorganic nutrients) in the sea (from coast to open ocean), attending their sources, fluxes, distribution and biological impact, and their sensitivity to changing environmental conditions (natural or anthropogenic). This research has always required of different multidisciplinary approaches and the development of parallel research areas such as environmental analytical chemistry, atmospheric chemistry and/or ecology. I am member of the Spanish State Research Agency (AEI) in the area of marine science (since 2018 to date) and represent Spain in the GEOTRACES scientific steering committee (starting in 2017) and in the marine working group of the International Arctic Science Committee (IASC) (starting in 2019).
