Lothar HelmLothar Helm was born in Gernsbach (Germany) in 1952. He studied physics at the University of Karlsruhe (Germany) and obtained his diploma degree in 1977. He remained in Karlsruhe for his Ph.D. research with Prof. H. G. Hertz and received his degree in physical chemistry in 1980. In 1980 he joined the laboratories of Prof. André Merbach at the University of Lausanne, Switzerland. From 1983 to 2001 he was maître denseignement et de recherche at the Faculty of Science of the University of Lausanne. In 2001 he moved, together with the whole chemistry department, from the University of Lausanne to the Ecole Polytechnique Fédérale de Lausanne (EPFL). Since 2006 he is adjunct professor at the Institute of Chemical Sciences and Engineering at EPFL and director of the NMR services of the institute.
From 2007 to 2011 he was director of the "Conférence du corps Enseignant" at EPFL. Since 2011 he is member of the School Assembly of EPFL (AE).

Daniel OberliDaniel Oberli was born in Switzerland in 1957. After completing his undergraduate education in the Physics department at EPFL he was awarded a Fulbright Fellowship to enter the graduate program in physics from the University of Illinois at Urbana-Champaign. He received his degree of Doctor of Philosophy in Physics in 1988. His thesis topic was the intersubband dynamics of photo excited carriers in two-dimensional semiconductor structures, for which he developed an original experimental approach based on time-resolved Raman scattering of electronic excitations. From 1988 to 1989, he was a post-doctoral fellow at AT&T Bell laboratories, where he pursued his research interests on the ultra fast time-resolved optical properties of semiconductor microstructures under the leadership of Dr. J. Shah. In 1990, he joined the Walter Schottky Institute of the Technical University of Munich, where he evidenced and studied Fano resonances in the optical excitation spectra of semiconductor quantum wells. Since 1994, he has been in the Institute of Physics of the School of Basic Sciences at EPFL. His main research activities include the electronic and optical properties of low-dimensional semiconductor structures, in particular quantum wires, quantum wells and dots, Raman scattering by phonons and electronic excitations in nanostructures and the radiative properties of exciton-polaritons in semiconductor microcavities, including the dynamics of exciton-polaritons and their interactions. He is a member of the American Physical Society.
