ENSI Executive Board
Dr. Hans Wanner
Director General: Hans Wanner (1955) studied chemistry at ETH Zurich and obtained his PhD in 1984. Following a research assignment at the PSI where he developed models for chemical processes in a deep geological repository, he joined the NEA of the OECD in Paris in 1986. He worked on the development of the international Thermochemical Database.
Dr. Georg Schwarz
Deputy Director : Georg Schwarz (1959) studied geophysics at ETH Zurich and was awarded his doctorate in 1991 by the Faculty of Environmental Sciences. Following assignments at ETH and a period as an independent software specialist, Georg Schwarz joined the former HSK in 1994. Since then, he has performed various roles, initially working as Head of IT Systems.
Dr. Felix Altorfer
Director, Staff of the Directorate: Felix Altorfer (born in 1965) studied physics at the ETH Zurich, and obtained his doctorate in 1994 at the Laboratory for Neutron Scattering at the ETH. After working in the US for four years at the NIST Center for Neutron Research, National Institute of Standards and Technology, he returned to Switzerland to undertake research at the Swiss Spallation Neutron Source (SINQ) of the PSI.
Dr. Georges Piller
Director, Radiation Protection Division: Georges Piller (1954) studied atomic and nuclear physics at the University of Fribourg obtaining his doctorate there in 1984. Following a 2-year research assignment on advanced pressurized water reactors working on the Proteus reactor of the Swiss Institute for Reactor Research (now the PSI), Georges Piller joined the Swiss Federal Office of Public Health (FOPH).
Dr. Ralph Schulz
Director, Safety Analyses Division: Ralph Schulz (1965) studied mechanical engineering at the RWTH Aachen University specialising in thermodynamics and obtained his doctorate at the end of 1997 from the Laboratory for Energy Systems at ETH Zurich. Following a period of three years with ALSTOM Power working on the development of combined cycle power plants, he joined the former HSK in 2000.
Jean-Claude Veyre
Director, Resources Division: Jean-Claude Veyre (born in 1957) studied electrical engineering at ETH Zurich, graduating with a degree in that subject in 1980. After his studies, he joined Haefely & Cie AG in Basel where he latterly held the post of Development Manager in the Network Components division. He then transferred to K. Swiss AG in Basel as Project Manager in the Engineering division.
Michael Wieser
Director, Waste Disposal Division: Michael Wieser graduated from the University of Applied Sciences in Biel/Bienne in 1992 with a degree in mechanical engineering. He then embarked on an international assignment as a Commissioning Engineer and Project Manager with ABB Power Generation/ALSTOM, working in the field of thermal power plants and control systems.
