Johann Cohen-Tanugi is a IN2P3 permanent researcher (grade CR1), who obtained his Physics doctorate in 2001, on experimental measurement of the CP asymmetry in the B-meson system with the BaBar detector. Followed two postdoctoral positions in Fermi, first at INFN-Pisa and then at SLAC, where he worked on the Large Area Telescope silicon tracker, and pursued several science topics in gamma-ray astroparticle physics, in particular Dark Matter Indirect detection, Gamma-Ray Bursts, Galactic sources of Cosmic Rays and large-scale diffuse emission. He joined LUPM in 2008.
