Curriculum Vitae



Research Interests

Researcher in marine microbiology and biochemistry 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 generally interested in combining chemical analyses with genome/transcriptome sequencing in order to identify specific metabolic pathways.
I recently predicted the biosynthetic pathways of two long chain diols (LCDs) and long chain hydroxy fatty acids (LCHFAs) in the biofuel alga Nannochloropsis spp. (doi:10.1093/pcp/pcz078) and I’m currently investigating the potential biotechnological applications of these two compounds classes.
In addition, I’m focusing on the adaptation of phytoplankton to heavy metal polluted environments. High throughput DNA sequencing techniques are shedding light on the genetic, metabolic, and chemical diversity of marine microbes but reconstructing the biosynthetic pathways for the biotechnologically relevant microbial products is the challenge of the coming decade. I´m generally interested in (1) microalgal mass culturing for the production of specific compounds as well as for phytodepuration, (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).
