Research Interests

The main topic of my research is the isolation and chemical characterization of bioactive molecules or new unexploited molecules, mainly from marine microorganisms, but also from other higher organisms, the so-called "natural products", The molecules of our interest include compounds with antimicrobial, anticancer, siderophore, biosurfactant activities, with potential biotechnological, pharmaceutical and nutraceutical applications.
Marine microorganisms are capable of producing numerous secondary metabolites, many of which, however, are encoded in their genome but are often not expressed in normal laboratory conditions, in fact they need the correct stimuli for them to be produced. For this reason, my approach is to use upstream genomic and bioinformatics analyses to identify biosynthetic clusters for the production of secondary metabolites. Subsequently, different metabolic responses are stimulated using the OSMAC approach, in order to activate as many metabolic pathways as possible, and therefore to produce the majority of secondary metabolites encoded in the genome. Subsequently, the complex metabolomes obtained from different stimuli are analysed using cutting-edge methodologies, which couple LC-HRMS analyses and chemo-informatics software, able to analyse thousands of metabolites in a short time, and provide an overview of the diversity chemical produced.
The metabolites of interest are purified by HPLC and characterized by MS and NMR in order to be tested.
