Valeria Ferrari is Professor of Theoretical Physics at Sapienza University of Rome (Italy), now retired. She has been Director of the Doctoral School in Physics of Sapienza, chaired the Virgo-EGO Scientific Forum and co-chaired the European Research Network COST Action GWverse. She has been a member of the Editorial Board of several international journals and of the Board of the International Society of General Relativity and Gravitation. She is a founding member of the Amaldi Research Center for Gravitational Physics at Sapienza. For more than forty years her research focused on black hole and stellar perturbations, and on gravitational wave sources. Leonardo Gualtieri is Professor of Theoretical Physics at University of Pisa (Italy). He is a member of the Board of the International Society of General Relativity and Gravitation and has been the coordinator of TEONGRAV, the INFN network of Italian groups studying gravitational wave sources. He works in the field of gravitational theory and phenomenology, with special focus on gravitational wave sources as probes of fundamental physics.

Paolo Pani is Professor of Theoretical Physics at Sapienza University of Rome (Italy) and Senior Fellow at Sapienza's School for Advanced Studies. He received the SIGRAV Prize from the Italian Society of General Relativity and Gravitational Physics for his studies on black hole physics and gravitational wave phenomenology, and their connections to fundamental physics.
