Curriculum Vitae


Research Intersts

I study the symbiosis between animal (host) and microorganisms, with a focus on the association found at the level of the gastrointestinal tract of marine invertebrates, and the host-microorganism interactions that are key elements for the host's physiology, development and functioning of this organ with implications for the immune system of the whole organism. My interest is particularly focused on the immune system which - together with the enteric nervous system - is responsible for the interaction and integration of signals between the host and the external environment (biotic and/or abiotic), generating a homeostatic state; the deregulation of this homeostasis is the basis of various gastric and nervous system diseases. The research activities in which I am involved pursue approaches in cellular and molecular biology, organismal physiology, developmental biology, microbiology and immunology. I am interested in studying the evolutionarily conserved processes that govern these interactions (and their effect on host physiology) or in highlighting species-specific features believed to underlie the evolution of physiological complexity in vertebrates, for example the development of the adaptive immune system. These investigations make the foundation for ecological and translational studies, allowing to investigate the effect of environmental changes or specific treatments on the beneficial microbial community and the consequent effect on the physiology and health of marine invertebrates.
