Research Interests

High-energy astrophysics, gravity:

  • Electromagnetic counterparts to gravitational wave sources
  • Theoretical study of the physics of relativistic jets (jets from galactic centers, from compact objects in binary systems and gamma-ray bursts)
  • Acceleration and composition of ultra-high-energy cosmic rays, associated neutrino emission
  • The nature of the central engine of gamma-ray bursts
