Physics

I work with cosmic rays of energies above 1EeV (Pierre Auger Observatory) and energies between 10GeV and 100TeV (Cherenkov Telescope Array - CTA). I am expertise in the field of Physics, with emphasis on the propagation of cosmic rays and interactions of particles and gamma rays. I am member of the Pierre Auger Cosmic Rays Observatory in Malargue, Argentina, since 2014 and member of the Cherenkov Telescope Array Observatory - CTA since 2015.
