The fields are particle physics, nuclear physics, astroparticle physics, cosmology, theoretical physics, energy (including nuclear reactor physics) and health. P2I teams are members of the very large research infrastructures recognized internationally. They have a unique know-how in cutting-edge technologies and also conduct original interdisciplinary research on societal issues (in particular health and energy).<\/p>\n\n\n\n<p><strong>Contact<\/strong>: <a href=\"mailto:frederic.deliot@cern.ch\" data-type=\"mailto\" data-id=\"mailto:frederic.deliot@cern.ch\">Fr\u00e9d\u00e9ric
