Research

My current and past research has focused on theoretical High Energy Astrophysics. In particular, it centers on the understanding of the prompt (short-lived gamma-ray) and afterglow (long-lasting X-ray, optical and radio emission) in Gamma-Ray Bursts (GRBs) and on many other topics related to this phenomenon (dissipation and radiation mechanisms, particle acceleration, magnetic field amplification).

My research has extended to understanding the radio emission from supernova remnants. It has also extended to tidal disruption events and I have focused on the multiwavelength modeling of jets from these events. I am currently also working on magneto-hydrodynamic simulations of relativistic jets.

I develop theoretical models – both analytical and numerical – and I compare them with observations, which are obtained with many satellites, such as Fermi, Swift, Chandra, XMM-Newton, HST, and optical and radio ground observatories. Comparing my models with observations is a key component of my research; I strive to use observations in all available wavelengths and I am in close contact with observers in the field.
