Claude Amsler
Claude Amsler was born in 1947 in Solothurn, Switzerland. He went to school in the nearby city of Biel-Bienne and obtained his Baccalaureate in Sciences at the Gymnase Francais. He studied experimental physics at the Swiss Federal Institute of Technology (ETH) in Zurich. He obtained his Ph.D. degree in 1975 with the first experiment performed in particle physics at the Paul Scherrer Institute (PSI), a measurement of pion scattering on polarized protons. In 1976 he joined Queen Mary College in London as a Research Associate and was delegated to TRIUMF in Vancouver to work on nucleon-nucleon scattering experiments. In 1978 he moved to Brookhaven National Laboratory on Long Island as a Research Assistent Professor from the University of New Mexico to work on antiproton experiments. In 1979 he returned to Europe as a CERN Fellow. After a brief leave at the University of Munich he joined in 1982 the Physics Institute of the University of Zurich, where he performed his habilitation. He was elected in 1987 as an Associate, then as a Full Professor in experimental physics, in 1999. So far he has supervised 15 Ph.D. theses at the Faculty of Sciences. Claude Amsler has been associated to CERN since 1980. He contributed to several projects, such as light meson spectroscopy in proton-antiproton annihilation with ASTERIX and CRYSTAL BARREL, production of antihydrogen with ATHENA, and a measurement of the neutrino magnetic moment at a nearby nuclear power plant. He is currently a Member of the CMS collaboration at the LHC, of the DIRAC II collaboration to study Kpi-atoms, and has plans for a liquid argon dark matter experiment. Between 1996 and 2003 he was coordinating high energy physics in Switzerland. He is presently a member of the Swiss National Research Council and represents his country in NuPECC. He is also a member of the Particle Data Group.
