# Stefano Vitale

Stefano Vitale (born 1951, Naples, Italy) is an Italian physicist and a retired professor of experimental physics at the University of Trento. He is known for his scientific contributions in the field of gravitational wave (GW) research and the successful management of international scientific projects.
In particular he has been the co-Principal Investigator of the cryogenic, resonant-bar GW detector AURIGA and the Principal Investigator of the LISA Technology Package, the sole instrument of ESA´s LISA Pathfinder mission. He continues to do scientific research and is Co-lead of the international LISA Consortium. LISA, the Laser Interferometer Space Antenna, is the future gravitational wave-observatory in space, led by ESA.
Stefano Vitale has served on many different committees. In particular he has been the chair of the Fundamental Physics Advisory group of Science Directorate of ESA, and the chair of ESA's Science Programme Committee, the delegate body that steers the mandatory agency science program.

## Career

Stefano Vitale received his Laurea in Physics at the University of Rome (now Università degli Studi di Roma "La Sapienza") in 1976 and was a research fellow at the University of Trento from 1977 to 1979. From 1980 to 1985 he was appointed Assistant Professor for Condensed matter physics at University of Trento, after which he became Associate Professor of Physics there. Since 1994 he was full Professor of Physics at the University of Trento and served 2001 to 2004 also as Deputy Rector (Prorettore Vicario). He retired from his Professorship on 30 September 2021.
In 1992 Stefano Vitale was visiting professor at the Department of Physics at the University of California at Berkeley and from 1997 to 1998 he also was Visiting Scholar at the University of California at Berkeley and Stanford University in California. Since 1985 Stefano Vitale is a research associate at the Istituto Nazionale di Fisica Nucleare (INFN).
During his career, Vitale served on many national and international academic bodies, managing scientific projects and communities and advocating for basic and applied research.

## Experimental gravitational wave research

Stefano Vitale got involved in experimental gravitational wave research in the late 1980s. From 1988 to 2001 and then again from 2005 until his retirement in 2021, he was Head of the Laboratory for Experimental Gravitation at the Department of Physics of the University of Trento where cutting edge technologies for gravitational wave observatories were developed and tested.
From 1989 to 2003 Vitale was the co-Principal Investigator of the cryogenic, resonant-bar GW detector AURIGA, by the Italian Istituto Nazionale di Fisica Nucleare, based in Legnaro. AURIGA has been the most sensitive of this kind of detectors, with the adoption of a three resonant mode configuration the design of which was led by Stefano Vitale.

### The LISA Pathfinder and LISA missions

In 2003 Vitale became the Principal Investigator of the LISA Technology Package, the sole instrument of the LISA Pathfinder mission of the European Space Agency. LISA Pathfinder was the precursor to the space-based GW detector LISA (Laser Interferometer Space Antenna), under development by ESA and NASA. LISA Pathfinder operated between 2015 and 2017, and successfully demonstrated the viability of the planned LISA Mission. Stefano Vitale led in particular, the design of the gravity reference sensor and the overall design of the experiment. LISA Pathfinder was decommissioned in July 2017 and the post of Principal Investigator duly expired in 2018.
Stefano Vitale is a member of the core international scientific team behind LISA, serving both within international scientific team for several years and on the executive committee of the LISA consortium. From 2016 to 2017 he was Co-Principal Investigator of LISA and since 2020 he is Co-Lead of the LISA Consortium. The LISA Consortium is a large international collaboration that combines the resources and expertise from scientists in many countries all over the world. Together with ESA and NASA, the LISA Consortium is working to bring the LISA Mission to fruition.
