My research focuses on the study of extreme astrophysical events, such as compact binary mergers and core-collapse supernovae. To this aim I design, implement, and analyze large-scale high-performance computing general-relativistic simulations. My goal is to use simulations, in combination with gravitational-waves and electromagnetic observations, to address fundamental questions such as: what is the nature matter at extreme densities? What is the origin of heavy elements? What is the fate of massive stars? I am also interested in the development of new computational techniques and in the study of the fundamental physical processes operating in these events.
