Personal profile
Research interests
am currently an associate professor in the physics department in Bar Ilan University.
My research focuses on theoretical high energy astrophysics. My present interests include dynamics and radiation processes in Gamma-ray bursts, X-ray emitting binaries, high energy cosmic rays and tidal disruption events. I work on broad band emission models, relativistic gas dynamics and nuclear processes. Further details can be found in the links above.
