Roberto Aloisio is a Professor at the Gran Sasso Science Institute, L'Aquila, Italy. His research is concentrated on studies at the boundaries between particle physics and astrophysics. His interests include the origin and propagation of cosmic rays, the possible indirect detection of dark matter, and, generally, nonthermal processes in astrophysics. He has also worked on theories with broken Lorentz invariance. Dr. Aloisio is involved in the activities of the High-Energy Astrophysics Group at the Arcetri Astrophysical Observatory and the Theory Group at the Gran Sasso National Laboratories.

Eugenio Coccia is Director of the Gran Sasso Science Institute and Professor of Physics at the University of Rome Tor Vergata, Italy. He is an experimental physicist with a focus on the detection of gravitational waves and an interest in neutrino physics and cosmic ray detectors. He has directed the EXPLORER experiment at CERN and leads the NAUTILUS experiment at the INFN Frascati Laboratories. He has been Director of the INFN Gran Sasso Laboratory (2003-2009), President of the Italian Society of General Relativity and Gravitational Physics (2000-2004), and Chair of the INFN Scientific Committee on Astroparticle Physics (2002-2003). He is currently the Chair of the Gravitational Wave International Committee (GWIC) and a member of the Council of the European Physical Society. In 2012 he was awarded the "Occhialini Medal" and Prize by the Institute of Physics (IOP), jointly with the Italian Physical Society.

Francesco Vissani earned a PhD in high-energy physics from SISSA in 1994 and is currently a Professor at the Gran Sasso Science Institute, L'Aquila, Italy. His interests focus on astrophysics, and in particular supernova neutrinos; very high energy neutrinos and gamma rays; connections between particle physics and astrophysics; cosmic rays; lepto/baryogenesis; manifestations of neutrino masses; flavor oscillations; other probes of neutrino masses; tests ofthe
