I am an internationally recognized expert on the physics of large-scales structures, including shocks, turbulence, cosmic ray acceleration and nonthermal radiation processes. I am the PI of large supercomputing projects, and I have realised the largest simulations of extragalactic magnetic fields. I am collaborating with all most important future radio surveys (with LOFAR, ASKAP, MEERKAT and SKA). I am undertaking the challenge of understanding the origin of cosmic magnetism, also with my ERC-founded Starting Grant (2017-2022).
