I am a TD researcher at INAF Osservatorio Astronomico di Roma studying high-energy astrophysical transients, particularly Gamma-Ray Bursts (GRBs). I completed my PhD in Astroparticle Physics at Gran Sasso Science Institute, where I focused on the origin of high-energy emission during the prompt and early afterglow phases of GRBs. My work combines theoretical modeling with multi-wavelength observations spanning from X-ray energies to very-high-energy gamma rays. I am especially interested in the transition between prompt and afterglow emission, and in extending multi-wavelength coverage of GRBs at early times by exploiting current and next-generation facilities. More broadly, I aim to use GRBs as laboratories for particle acceleration, relativistic plasma physics, and multi-messenger astrophysics.
Alongside my research, I am also actively involved in public outreach with the association IDeAS, with the goal of making science accessible to a wider audience.
