Bruno Giacomazzo's main research interest is in the numerical solution of the equations of general relativistic magnetohydrodynamics (MHD) which describe the evolution of compact objects, such as neutron stars and black holes, in presence of magnetic fields. To this purpose he developed a new numerical code, called WhiskyMHD, which solves the equations of fully general relativistic MHD on a dynamical curved background. He is also the author of the first exact solver for Riemann problems in relativistic MHD with generic initial states. This exact solution has been already used by several groups in the world to test special and general relativistic MHD codes. Bruno Giacomazzo received his PhD in Astrophysics from SISSA (Trieste, Italy) on October 2006, worked for 3 years at the Max Planck Institute for Gravitational Physics (AEI, Potsdam, Germany), 2 years at the University of Maryland and NASA Goddard Space Flight Center (USA), 2 years at JILA (University of Colorado Boulder, USA), and 6 years at the University of Trento (Italy). He is currently an associate professor at the Department of Physics of the University of Milano-Bicocca (Italy).
