My research interests are on the ecology of phytoplankton in Portuguese coastal waters, with emphasis on HABs. I am particularly interested in understanding the ecological significance of different life-cycle stages in HAB bloom dynamics and species dispersal. As part of my research, I am building at UL-MARE a culture collection (ALISU) of marine microalgae from Portuguese coastal waters. I am elected Council member of the International Society for the Study of Harmful Algae (ISSHA).
