# Stavros Katsanevas

Stavros Katsanevas (1953 – 27 November 2022) was a Greek-French astrophysicist who was director of the European Gravitational Observatory, professor (Exceptional Class) at the Université Paris Cité, former director of the AstroParticle and Cosmology (APC) laboratory and former chairman of the Astroparticle Physics European Consortium (APPEC). In 2000, he received for his work on supersymmetry the Physics Prize from the Academy of Athens. In 2011, he was awarded the Ordre National du Merite. He was an ordinary member of Academy of Europe, Earth and Cosmic Sciences since 2019.

## Education and work

Katsanevas was born in Athens, Greece, where he did his undergraduate studies in physics at the University of Athens. He obtained a doctorate "of 3rd cycle" from University of Paris XI and a PhD from the University of Athens, where he was later a lecturer and an associate professor (1982–1996). He has spent three years as a postdoc at the Fermi National Laboratory. He also worked at CERN, as a CERN Fellow, CERN Associate Scientist and as CERN Corresponding fellow. He then moved (1996–2002) as a professor to France to the Université de Lyon I Claude Bernard. In 2002, he became Deputy Scientific Director of IN2P3/CNRS for the field of Neutrino and Astroparticle Physics (until 2012), transferring at the same time to the Université Paris VII Denis Diderot, where he was Professor Exceptional Class. Since 2018, he was director of the European Gravitational Observatory near Pisa.
From 2000, Katsanevas held the following positions:
* Director of the European Gravitational Observatory (2018–2023)
* Director of the Astroparticle and Cosmology Laboratory of CNRS / IN2P3 (2014–2017)
* Chairman of the Astroparticle Physics European Consortium (APPEC)
* Deputy Director of IN2P3/CNRS responsible for Neutrino, Cosmology and Astroparticle Physics (2002–2012)
* Director of the CNRS interdisciplinary program "Astroparticle Physics" (2002–2010)
* Chairman of the EU funded agency consortium AStroparticle Physics European Research Area NETwork (ASPERA)
* Principal Investigator (in a total of 15) of the Institute for the Physics and Mathematics of the Universe at Tokyo (2007–2018)
* President of the council of the European Gravitational Observatory (EGO) host of the VIRGO gravitational wave antenna (2003–2008 and 2011–2017)
Katsanevas was also a member of the following committees:
* Steering Committee of Astroparticle Physics European Coordination (ApPEC)(2002–20??)
* AstroParticle Physics International Forum (APIF) of OECD (2010–2014)
* European Strategy Group as representative of APPEC (2011–2013)
* CERN Super Proton Synchrotron (SPS) Committee (SPSC) (2008–2010)
* PaNAGIC (Particle and Nuclear Astrophysics and Gravitation International Committee) astroparticle coordination - IUPAP working group (2005–2012)
* Evaluation Committee for Space Research and Exploration and Inter-Organism Committee of CNES (National Centre of Space Studies, France) (2002–2012)
* Scientific council (chairman) of IFAE/Barcelona (2009–2013)
