Salvatore Viola received a PhD in Physics in 2013 at the University of Catania. From 2013 to 2020 he worked as a researcher at INFN - LNS (Istituto Nazionale di Fisica Nucleare - Laboratori Nazionali del Sud). The main research activities were carried out in the field of underwater acoustics for particle physics applications. He coordinated the development of an acoustic positioning system for a km3-scale underwater neutrino telescope, as member of the KM3NeT Collaboration. In the framework of the EMSO (European Multidisciplinary Seafloor and water column Observatory) and SMO (Submarine Multidisciplinary Observatory) projects, he was responsible for the activities aimed at the analysis of underwater noise and for the development of algorithms for the detection and tracking of underwater acoustic sources. From January 2020 to September 2021 he worked as a scientist at the CMRE (Center for Maritime Research and Experimentation) of the NATO's STO (Science and Technology Organization). He is currently a research scientist at the INFN-LNS.
