The Galician Institute for High Energy Physics (IGFAE) of the University of Santiago de Compostela has a profile research focused on Particle, Astroparticle and Nuclear Physics, with both theoretical activities and participation in experimental programs like the LHCb experiment at the LHC at CERN, the Auger experiment, the NEXT experiment and several nuclear physics experiments like R3B at FAIR or nTOF at ISOLDE. The institute has 30 permanent members, with 7 full professors. At present, the particle physics phenomenology group is formed by six theoretical physicists (plus two emeritus), 3 postdocs and 5 PhD students, with activities in QCD perturbation theory applied to high energy hadronic and nuclear processes, non-perturbative techniques applied to dense astrophysical objects and nuclear structure, and phenomenology of high-energy hadronic and nuclear collisions. The Institute was recognised in 2016 as Unidad de Excelencia María de Maetzu by the Spanish government.
