Research interests

My main research interests focus on life cycles of unicellular marine microalgae, on the role they have in the ecology, population dynamics and genetic structure of the species. Phytoplankton cells undergo transitions between an actively growing phase, during which biomass is increasing, and other life phases in which cells are dormant or quiescent, undergo sexual reproduction or die. These phase transitions represent an organism’s life cycle. In collaboration with PhD students and colleagues, we have investigated various aspects of the life cycle of the marine diatom Pseudo-nitzschia multistriata, including the factors that induce the sexual phase and the occurrence of sex in the natural environment through experimental and modelling approaches. We are now using transcriptomic approaches to gain insights on the mating system of this diatom that has a heterothallic life cycle. We also studied the germination dynamics of diatoms spores at the LTER-MC station in the Gulf of Naples and plan to investigate the cues that induce the formation and hatching of these resting stages.
Phytoplankton biodiversity is another topic of interest, where we couple the classical morpho-taxonomy with molecular approaches to better define species and populations. Research is focused at the LTER-MC station, where we integrate the study of the phytoplankton community with NGS data, and where we carry out a multi-annual study of the population genetic structure of the diatom Pseudo-nitzschia multistriata.
