Riccardo received his PhD from the Max Planck Institute for Extraterrestrial Physics (Germany) in 2021 and, after a NHFP Einstein Fellowship at MIT, he joined the BHI as a Fellow. Riccardo’s research focuses on studying transient and persistent accretion events onto black holes of different masses. Most of his current efforts are dedicated to the discovery and study of a new population of X-ray flaring galaxies, the so-called quasi-periodic eruptions.
