Research Interests
My research interests focus on marine biotechnology, ecotoxicology and molecular ecology. Marine natural products (MNPs) are very interesting for their ecological and biotechnological value. In fact, MNPs possess several biological activities, such as anti-cancer, anti-bacterial, anti-viral, antifungal, anti-oxidant and anti-aging, that are useful for pharmaceutical, nutraceutical and cosmeceutical purposes. I am interested in MNPs from marine invertebrates and their symbionts by applying molecular approaches, such as, metagenomics, transcriptomics and genetic engineering. For instance, metagenomic approaches are able to predict classifiable secondary metabolite biosynthetic gene clusters (BGCs), synthetizing various secondary metabolites such as, terpenes, polyketides, bacteriocins and nonribosomal peptides. It is well known that a conspicuous amount of bioactive secondary metabolites is synthetized by the symbiotic community living within marine invertebrates. This strict association is often fundamental for the survival and fitness of both organisms. The number of natural products discovered from marine microorganisms has sharply increased over the past decade. This reservoir of bioactive microbes offers exciting alternatives to the often unprofitable and complicated chemical synthesis of natural products, and the unsustainable harvest of slow-growing and declining wild populations.
I am also interested in ecotoxicological studies evaluating the stress response of marine invertebrates to diverse natural and anthropogenic-related compounds. Experimental pipelines principally include gene expression analyses and transcriptomics to measure the number of Differentially Expressed (DE) genes in control and treated samples, identification of the molecular pathway activated in response to the exposure of such stressors and validation of the biological cascade at the protein level through biochemical approaches.
