During my degree studies in Rome I became passionate about Cosmology, the science that studies the origin, evolution and content of our Universe. I started using observation of the Cosmic Microwave Background (CMB), the faint afterglow of the Big Bang, to learn about cosmological models and possible departures from “standard” physics. Ever since then, I have been working at the development of data analysis techniques, algorithms and software to extract information from complex cosmological observations. Being an associate investigator of the ESA space missions Planck and Euclid, I had the opportunity to collaborate with scientists from all over the world, and mobility became a key aspect of my career, and my life! I was an associate researcher at IFCA in Spain, at the Cambridge University in UK, and now I have moved back to Rome, where it all started, to work at the ASI Science Data Centre.
