Dr. Bruno has over 15 years of experience in experimental astroparticle physics. His scientific activities focus on the investigation of the origin and the propagation of cosmic rays in the Galaxy, the heliosphere and the terrestrial magnetosphere, by means of ground- and space-based detectors. He's actively involved in the modeling of solar energetic particle events aimed to space-weather predictions, and in the development and calibration of new particle detectors.
