Research Interests
Marine microbiologist and biogeochemist with a broad research experience in phytoplankton taxonomy and ecology, I joined the department of marine biotechnology in May 2019. I focus on the use of microalgae for distinct biotechnological applications. I’m focusing on the diversity and adaptation of microalgae and other microbial eukaryotes to polluted environments and their potential use for bioremediation and water treatment. We recently isolated and brought in culture several microalgal strains from coastal sediment highly contaminated by heavy metals and hydrocarbons and identified a green alga, identified as Tetraselmis convolutae, able to tolerate and uptake heavy metals (https://doi.org/10.3390/microorganisms10122445). In addition I’m also focusing on the production of secondary metabolites from the oleaginous alga Nannochloropsis. Modern sequencing techniques are shedding light on the genetic, metabolic, and chemical diversity of marine microbes as well as their ability to degrade or uptake pollutants. Reconstructing such biosynthetic pathways is the challenge of the coming decade. I´m generally interested in (1) microalgal mass culturing to produce specific compounds as well as for phycoremediation, (2) reconstructing metabolic pathways, and (3) searching novel microbial products from aquatic phytoplankton using genomic/transcriptomic/bioinformatic approaches.
Biography
I graduated in 2004 from Parthenope University, Naples after a master thesis in phytoplankton taxonomy and morphology. Then I did a PhD in marine biogeochemistry at the university of Southampton where I focused on trace metal cycling in marine aggregates. Finally, I carried out three distinct postdoctoral research projects in Roscoff (France, 2009-2012, phytoplankton diversity and ecology), Adelaide (Australia, 2012-2014, biofouling microbes), and Texel (Netherlands, 2014-2018, biosynthetic pathways of microalgal lipids).
