Alessandro de Angelis is a high energy physicist and astrophysicist. Professor at the Universities of Udine, Padua and Lisbon, he is currently the Principal Investigator of the proposed space mission e-ASTROGAM and for many years has been director of research at INFN Padua, and scientific coordinator and chairman of the board managing the MAGIC gamma-ray telescopes in the Canary Island of La Palma. His main research interest is on fundamental physics, especially astrophysics and elementary particle physics at accelerators. He graduated from Padua, was employed at CERN for seven years in the 1990s ending as a staff member, and  later was among the founding members of  NASA's Fermi gamma-ray telescope. His original scientific contributions have been mostly related to electromagnetic calorimeters, advanced trigger systems, QCD, artificial neural networks, and to the study of the cosmological propagation of photons. He has taught electromagnetism and astroparticle physics in Italy and Portugal and has been a visiting professor in the ICRR of Tokyo, at the Max-Planck Institute in Munich, and at the University of Paris VI. 

Mário Pimenta is a high energy physicist and astrophysicist.  Professor at the Instituto Superior Técnico  of the University of Lisbon, he is currently the  president of the Portuguese national organization for Particle and Astroparticle Physics, coordinator of the international PhD doctoral network IDPASC, and the representative for Portugal at the Pierre Auger Observatory in Argentina. Formerly member of the WA72, WA74, NA38 and DELPHI experiments at CERN and of the EUSO collaboration at ESA, his main interest of research is on high-energy physics, especially cosmic rays of extremely high energy and development of detectors for astroparticle physics. He graduated from Lisbon and Paris VI, and was employed at CERN in the late 1980s. His original contributions have been mostly related to advanced trigger systems, search for new particles, hadronic interactions at extremely high energies, and recently to innovative particle detectors. He has taught general physics and particle physics in Portugal, has lectured at the University of Udine and has been visiting professor at SISSA/ISAS in Trieste.
