The Cosmic Microwave Background encodes the universe's earliest moments. My work targets the B-mode polarization signal — a faint imprint of primordial gravitational waves generated during cosmic inflation. To detect this elusive signal, my research focuses on instrument definition and requirements, alongside advanced data analysis techniques to disentangle the primordial signal from instrumental systematics and astrophysical foregrounds such as galactic dust and synchrotron emission.

LiteBIRD Space Mission

LiteBIRD (JAXA L-class, launch ~mid-2030s) will operate from the Sun–Earth L2 point for three years, covering 15 frequency bands between 34 and 448 GHz across three telescopes. I contribute to systematic effect characterisation and mitigation, ensuring optical components meet the mission's unprecedented sensitivity requirement of ~2.2 µK·arcmin.

I regularly participate in public engagement activities organised by the INAF Astronomical Observatory of Rome at both the Monte Porzio Catone and Monte Mario sites. These include public observation nights, guided talks and school outreach programmes — making frontier astrophysics accessible and inspiring for audiences of all ages.

Outside the lab, I compete in the Italian volleyball federation (FIPAV Lazio) at regional level. In parallel, I coach a youth male team, channelling my passion for sport into mentoring the next generation of players. Both roles reflect my deep commitment to teamwork, discipline, and community beyond academia.
