Director of the Gran Sasso Science Institute (INFN Center for Advanced Studies) and full professor of Physics at the University of Rome Tor Vergata. Experimental physicist, his field of activity is astroparticle physics, with a focus on the detection and study of gravitational waves.
He graduated in Physics in Rome University, working in the group of Edoardo Amaldi and Guido Pizzella. He was post-Doc and Fellow at CERN (1981-1985), research scientist (1985-1987) and associate professor (1988-1999) at the University of Rome Tor Vergata. He spent various periods of research activity at CERN, at the Kamerlingh Onnes Laboratory in Leiden and at the INFN Laboratories of Frascati and Gran Sasso. He directed the EXPLORER experiment at CERN and leads the NAUTILUS experiment at the INFN Frascati Laboratories on gravitational-wave detection. He is a member of the VIRGO Collaboration, operating the largest European gravitational-wave laser interferometer detector. He was the 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 was Chair of the Gravitational Wave International Committee (GWIC) and council member of the European Physical Society. At present he is council member in the Italian Physical Society and member of the executive board in the National Institute for Astrophysics.
He was awarded the "Occhialini Medal" and Prize by the Institute of Physics (IOP), jointly with the Italian Physical Society in 2012 and the honor “Commendatore dell’Ordine al Merito della Repubblica Italiana” by President Giorgio Napolitano in 2011. He was appointed by the Prime Minister in the Committee of Experts for the research policy in 2014 and elected in the “Academia Europaea” in 2015.
