Curriculum Vitae

 


Research Interests

I am interested in the evolution of genome function and of the molecular mechanisms making functional the information encoded in the genome of marine organisms. I use multidisciplinary approaches integrating functional genomics, transcriptomics, epigenetics, molecular and physiological analysis, to investigate the regulation of cell fate decisions in biological processes as diverse as the development of embryonic structures (i.e.: how undifferentiated cells choose between different fates) and the plastic mechanisms of cell response and adaptation to the dynamic changes of marine ecosystems (i.e.: the regulation of diel cell activity and of life cycle decision in phytoplanktonic organisms). Exploring the diversity of marine organisms represents a powerful tool to provide new perspectives in the molecular regulation of cellular functions and their understanding has the potential to help explaining the evolution of life on our planet.
