She is a Full Professor of Marine Sciences (Ph.D. in Biological Oceanography 1996). Her main research interests lie in the impacts of global change on aquatic food webs and biodiversity, such as warming, acidification, invasive species, jellyfish, and plastic pollution of the seas, from tropical to temperate areas. Her research and education projects have focused on sustainable blue growth to address the need for an ecological transition in the blue economy, and in sustainable Food production. She coordinates the Ecoreach research group - Ecology and Restoration of Riverine, Estuarine, and Coastal Habitats. She is responsible for the planktonic time series in the South Iberian Lower Guadiana Station (https://www.st.nmfs.noaa.gov/copepod/time-series/pt-30201/) with data since 1997.
