Research Interests

Biofluorescence is a physical process that occurs when a specific wavelength of light is absorbed by fluorescent proteins (FP) converting it into longer wavelengths with less energy and resulting in a different colour light.
A wide variety of marine organisms is biofluorescent. This phenomenon has an important role in intra and inter-species communication, in meetings for reproductive purposes and for predator-prey interactions. While it was believed that only certain marine organisms (i.e corals, jellyfish) had the ability to emit light into fluorescence, it was recently discovered that far more numerous groups of animals own this property. Therefore the search for new proteins expressed in different marine organisms is very active.
The research on FPs in marine organisms is a transverse field, being of great interest for biotechnological aspects but the evolutionary biology and ecology of organism bearing fluorescence are still largely unexplored.
We want to extend the search of FPs to phylogenetically distant organisms to identify FPs with fluorescence characteristics completely and/or slightly different from those already known. The study will include unicellular and multicellular planktonic organisms (e.g. tunicates, diatoms, copepods, ctenophores, scyphozoans), benthic (e.g., macroalgae, sea slugs, anthozoans) and fish species. Simultaneously, we want to better understand the ecological function of FPs and how they evolved in the animal kingdom.
