The research activities of CHIPP are best described by the three pillars "High Energy Frontier", "Neutrino Physics" and "Astro-Particle Physics and Cosmology". The previous two schools focused was on High Energy and then Neutrino physics. Therefore, this third school will focus on Astro-Particle Physics and Cosmology. These focus lectures are complemented by shorter lecture series on LHC and Neutrio physics. All lectures are given by international and national experts.
