Biographie:
Helmut H. Telle received BSc, MSc and PhD degrees in physics from the University of Koln (Germany), in 1972, 1974 and 1979 respectively. Between 1980 and 1984 he spent research periods at the Department of Chemistry, University of Toronto (Canada), the Centre d' Etude Nucleaire de Saclay (France) and the Laboratoire des Interactions Ioniques, University of Marseille (France), Where he was mainly engaged in research on molecular reaction dynamics exploiting laser spectroscopic techniques. Since 1984 he has been Professor for Laser Physics in the Department of Physics, Swansea University (Wales, UK), where he has pursued research and development of laser systems and spectroscopic techniques for trace detection of atomic and molecular species, applied to analytical problems in industry, biomedicine and the environment. His expertise includes the techniques of laser-induced breakdown spectroscopy (LIBS), tuneable diode laser absorption spectroscopy (TDLAS), resonant ionization mass spectrometry (RIMS) and Raman and Near-field scanning optical microscopy (NSOM). More recently, he has once again returned to his roots associated with fundamental aspects in atomic and molecular physics, ranging from precision spectroscopy of exotic species, like positronium and anti-hydrogen, to probing of reactions at surfaces utilizing ultra-short laser pulses. He has held visiting appointments at the Centro de Investigacion en Optica, Leon (Mexico), the Universidad Complutense de Madrid (Spain) and at the Katholieke Universiteit Leuven (Belgium).

Angel Gonzalez Urena obtained a chemistry degree from the University of Granada (Spain) in 1968, followed by a PhD in Physical Chemistry from the Complutense University (Madrid, Spain) in 1972. During the period 1972-1974 he worked in the fields of molecular beam and reaction dynamics at the Universities of Madison (Wisconsin, USA) and Austin (Texas, USA), and in later years at universities in the UK. He became Associate Professor in Chemical Physics in 1974 and Full Professor in 1983, both at the Completeness University of Madrid. His research interests focus mainly on gas-phase, cluster and surface reaction dynamics, using molecular beam and laser techniques. He was one of the?pioneers in measuring threshold energies in chemical reactivity when changing the translational and electronic energy of the reactants, as well as in the measurements of high-resolution spectroscopy in intra-cluster reactions. More recently, his interests have branched out into the application of laser technologies to Analytical Chemistry, Environmental Chemistry, Biology and Food Science. he is the head of the Department of Molecular Beams and Lasers at the Institution Pluridisciplinar (Complutense University, Madrid)...
