We study various topics in Theoretical Astrophysics, with a focus on High-Energy and Particle Astrophysics. Our goal is to understand the physical processes governing the observed astrophysical phenomena, in particular at high energies. 

A significant fraction of my time is devoted to leading the UV satellite mission ULTRASAT, which is aiming at revolutionizing the study of astronomical transients.
