I have been working with Legionella and Legionnaires’ disease for more than 20 years, acquiring great experience in diagnosis, typing and outbreak investigations. My skill in molecular biology has allowed me to approach any study on Legionella, prone to any innovative technological progress. In recent years I have implemented a genomic approach aimed at better characterizing the isolates and identifying more precisely the origin of the infection occurred in Italy, as well as the emergence of prominent pathogenic strains isolated in our country. Additionally, my participation in the drafting the Italian guidelines for the prevention and control of legionellosis gave me the opportunity to learn more about all the aspects concerning how water systems work and disinfection treatments. Finally, studies on the microbiome of building water systems have opened new possible scenarios in my research on the ecology of Legionella aimed to better understand the interactions of this bacterium with the artificial environment and to identify new solutions to manage its control. I participated to numerous training courses as a teacher, and I have been responsible for research projects. Currently I’m member of ESCMID Study group for Legionella Infection (ESGLI) Executive committee and I’m Operational contact point for Legionella microbiology at ECDC. I published more than 50 manuscripts in international scientific journals.
