Chairman of the Supervisory Board
From 1979 to 1985 Engelen worked at CERN, before accepting a position at Nikhef (National Institute for Subatomic Physics) in 1985. He became professor of Experimental Physics at the University of Amsterdam in 1987. At CERN and DESY (Hamburg) he carried out experiments in the area of the strong interaction, hard photoproduction and dispersion in deep inelastic scattering. He also developed initiatives for research in the field of astroparticle physics.
From 2001 to 2003 Engelen was director of Nikhef (the Dutch National Institute for Subatomic Physics) and in 2004 he became the scientific director and deputy director-general of CERN, a position he held until 2008. His responsibilities there included overseeing the construction and commissioning of the new LHC particle accelerator and the associated experimental set-ups.
In 2009 Engelen returned to The Netherlands and was nominated president of the Netherlands Organisation for Scientific Research, whilst holding a part-time chair in experimental high energy physics at the University of Amsterdam.
Physics study at Nijmegen University (presently Radboud University) starting September 1967, Doctoral Exam February 1973.
Research Appointment (20% for teaching) at Nijmegen University; Ph.D. February 1979 (Nijmegen University).
March 1979 –February 1985: CERN (the European Laboratory for Particle Physics - Geneva, Switzerland), Fellow and Staff Member.
March 1985 – present: Staff Physicist at NIKHEF, since 1987 Full Professor of Physics at the University of Amsterdam.
1 July 2001 – 31 December 2003: Director of NIKHEF, National Institute for High Energy and Nuclear Physics (Amsterdam, The Netherlands).
1 January 2004 – 31 December 2008: Chief Scientific Officer (Scientific Director) and Deputy DirectorGeneral of CERN, the European Laboratory for Particle Physics. CERN is a European Intergovernmental
Research Organization (20 European Members States plus ‘Observer States’ a.o. India, Israel, Japan, Russia, USA) – the annual budget is approximately 1 Billion CHF.
As of 1 January 2009: President of the Governing Board of the Netherlands Organization for Scientific Research (NWO). He is former Vice President of EUROHORCs (European association of the heads of
research funding organisations (RFO) and research performing organisations (RPO) and current member of the Steering Committee of the European Science Foundation.
Member of various national and international scientific committees and councils.
Corresponding member of the Royal Netherlands Academy of Arts and Sciences.
(Co-)author of 200 scientific publications. Scientific projects so far: X42 (K-p interactions); NA14 (p hard
interactions); ZEUS (ep deep inelastic scattering); ANTARES (detection of cosmic neutrinos). Member of
CERN’s Super Proton Synchrotron Committee (1991-1995) and member of CERN’s Large Hadron Collider
Committee (1995-2001), from 1997-2001 chairman of this committee and as such an ex officio member
of CERN’s Research Board and of CERN Council’s Scientific Policy Committee.
