I am a marine microbiologist and biogeochemist. My research is focused in understanding the relationship between the distribution of nutrients in the sea and the elemental composition of phytoplankton. I use energy-dispersive X-ray microanalysis (EDS, EDX or XRMA) to study the elemental composition at a single-cell level. I joined the Department of Chemical and Biological Engineering funded with a Marie Skłodowska-Curie Individual Fellowship, to advance in the study of the third generation of biofuels, studying nutrient allocation in marine phytoplankton, including diatoms, dinoflagellates and coccolitophorids. In the sea, these three groups of phytoplankton have a leading role in primary production (i.e. carbon fixation), and are main contributors of organic matter export to the deep ocean (i.e. carbon sequestration).
