Curriculum Vitae

Research interests

My research interest is on microalgae biodiversity and its role in regulating the structure and functioning of marine ecosystems. I participated in projects on distribution and ecology of phytoplankton in different geographic areas, but my research is primarily focused on the Long Term Ecological Research station MareChiara (LTER-MC), where I am in charge for phytoplankton data series since 1994.
In collaboration with other colleagues, in the course of 30 years of study of the LTER-MC, we have investigated phytoplankton diversity in the Gulf of Naples, where we have recorded more than 800 species, and described about 30 species new to the science. More recently, we have integrated the study of phytoplankton ecology with NGS analyses, which have shown that molecular approaches only allow a partial interpretation of the huge existing diversity of protists because a large portion of sequences can still not be attributed to any known organism. We are now using an integrated approach, supported by improved cultivation and/or single cells analyses, in order to obtain molecular data combined with detailed morphological information for a high number of species. The addition to reference databases of taxonomically validated benchmark sequences will considerably improve the quality of NGS analyses and its application to ecological and biomonitoring programs.
I am also involved in training, as organiser and teacher in international advanced courses on phytoplankton taxonomy. I consider this activity fundamental in order to give my contribution to the creation of new generations of taxonomists able to combine different approaches for an integrated definition of phytoplankton species.
