Giuseppina Rea, PhD in Biology, has experience in plant molecular biology, biochemistry, biotechnology and protein engineering applied to fundamental research and technological transfer.
Research activities are mainly focused on the molecular mechanisms and signal networks involved in the light events of photosynthesis and the structure/function relationships of the pigment-protein complexes involved in these processes. These studies are mainly performed on the green alga Chlamydomonas reinhardtii and the purple bacterium Rhodobacter sphaeroides to produce strains with improved photosynthetic performance and exploit them as biological farms in nutraceutical applications, life regenerative supporting system in space research and bio-sensing elements in development of biosensors for food quality assessment and environmental monitoring. The activity covers a wide variety of methodologies: i)computational-aided bioengineering of photosynthetic proteins; ii) site-directed and random mutagenesis targeted to the D1 reaction center protein; iii)chloroplast transformation; iv)isolation and expression profile of genes involved in different metabolic processes; v) metabolite profiling of photosynthesis functional metabolites; vi)designing of miniaturised optical biosensors for multiparametric fluorescence measurements of different photosynthesis-based biomediators.
