Luc ThévenazLuc Thévenaz received in 1982 the M.Sc. degree in astrophysics from the Observatory of Geneva, Switzerland, and in 1988 the Ph.D. degree in physics from the University of Geneva, Switzerland. He developed at this moment his field of expertise, i.e. fibre optics. In 1988 he joined the Swiss Federal Institute of Technology of Lausanne (EPFL) where he currently leads a research group involved in photonics, namely fibre optics and optical sensing. Research topics include Brillouin-scattering fibre sensors, nonlinear fibre optics, slow & fast light and laser spectroscopy in gases. His main achievements are: - the invention of a novel configuration for distributed Brillouin fibre sensing based on a single laser source, resulting in a high intrinsic stability making for the first time field measurements possible, - the development of a photoacoustic gas trace sensor using a near infra-red semiconductor laser, detecting a gas concentration at the ppb level, - the first experimental demonstration of optically-controlled slow & fast light in optical fibres, realized at ambient temperature and operating at any wavelength since based on stimulated Brillouin scattering. The first negative group velocity of light was also realized in optical fibres using this approach. In 1991, he visited the PUC University in Rio de Janeiro, Brazil where he worked on the generation of picosecond pulses in semiconductor lasers. In 1991-1992 he stayed at Stanford University, USA, where he participated in the development of a Brillouin laser gyroscope. He joined in 1998 the company Orbisphere Laboratories SA in Neuchâtel, Switzerland, as Expert Scientist to develop gas trace sensors based on photoacoustic laser spectroscopy. In 1998 and 1999 he visited the Korea Advanced Institute of Science and Technology (KAIST) in Daejon, South Korea, where he worked on fibre laser current sensors. In 2000 he co-founded the spin-off company Omnisens that is developing and commercializing advanced photonic instrumentation. In 2007 he visited Tel Aviv University where he studied the all-optical control of polarization in optical fibres. During winter 2010 he stayed at the University of Sydney where he studied applications of stimulated Brillouin scattering in chalcogenide waveguides. In 2014 he stayed at the Polytechnic University of Valencia where he worked on microwave applications of stimulated Brillouin scattering. He was member of the Consortium in the FP7 European Project GOSPEL "Governing the speed of light", was Chairman of the European COST Action 299 "FIDES: Optical Fibres for New Challenges Facing the Information Society" and is author or co-author of some 480 publications and 12 patents. He is now Coordinator of the H2020 Marie Skłodowska-Curie Innovative Training Networks FINESSE (FIbre NErve Systems for Sensing). He is co-Executive Editor-in-Chief of the journal "Nature Light: Science & Applications" and is Member of the Editorial Board (Associate Editor) for the journal "APL Photonics" & "Laser & Photonics Reviews". He is also Fellow of both the IEEE and the Optical Society (OSA).
Heinrich HofmannOriginaire de Mellingen (AG), Heinrich Hofmann est né en 1953. Après des études d'ingénieur en soudures (Ing. grad.) à Duisburg (D), et d'ingénieur en science des matériaux à la Technische Hochschule de Berlin, il obtient le titre de docteur ingénieur en 1983 pour une thèse dans le domaine des matériaux.De 1983 à 1985, il travaille comme assistant scientifique au Laboratoire de Technologie des Poudres de l'Institut Max Planck pour la science des matériaux à Stuttgart. En 1985 il entre au Centre de Recherche et Développement d'Alusuisse-Lonza à Neuhausen-am-Rheinfall, en tant qu'ingénieur consacré à la recherche dans l'étude et le développement des procédés de synthèse des poudres céramiques.En 1993 il entre à l'EPFL en tant que professeur extraordinaire et directeur du Laboratoire de technologie des poudres du Départmeent des matériaux. Son enseignement porte sur les céramiques I (procédés) et les phénomènes de transfert. Son domaine de recherche couvre la synthèse des poudres minérales, leur caractérisation et la modification des surfaces, ainsi que la mise en forme et le frittage. Ses recherches incluent aussi les matériaux nanostructurés (composites semi-conducteurs et polymères) et la métallurgie des poudres. Hofmann Heinrich, Prof. Dr.-Ing. got his PhD in Material Science with a thesis prepared at the Powder Metallurgy Laboratory at the Max Planck Institute in Stuttgart. In 1985 he joins the R&D center of Alusuisse-Lonza Services AG, at Neuhausen-am-Rheinfall. In 1993 he joins the Swiss Federal Institute of Technology as Professor and Director of the Powder Technology Laboratory at the Department of Materials science and engineering. His research area includes the synthesis of nanostructured materials based on nanoparticles and the modification of surfaces with nanoparticles using colloidal methods. The fields of application of such materials are medical and biological, (drug delivery, hyperthermia, cell separation, biosensors), electronics and sensors.
Jérôme BaudryJérôme Baudry is a historian of science and technology. Since 2019, he is a tenure-track assistant professor at EPFL, where he heads the Laboratory for the History of Science and Technology (LHST) and manages the UNIL-EPFL Collection of Scientific Instruments. He studied history, mathematics, sociology and economics in Paris, before receiving a PhD in the history of science at Harvard University. His research interests include the history of intellectual property, the role of the visual in science and technology, and the history and sociology of public participation in science. He is particularly interested in developing and experimenting with new tools and methods — especially digital and computational — for historical research.
Simon François Dumas PrimbaultSimon holds a PhD in the history of science from the joint programme of the European University Institute (EUI, Florence) and the École des hautes études en sciences sociales (EHESS, Paris). His doctoral dissertation focused on the drafts and working papers belonging to two natural philosophers of the second half of the 17th century – Galileo’s last disciple Vincenzio Viviani in Florence and Gottfried Wilhelm Leibniz in Hannover – and could be described as a work of historical anthropology of knowledge.
By addressing the ink-and-paper materiality of these supposedly purely intellectual operations that scatter the mechanical and physico-mathematical papers of Viviani and Leibniz, he aims at seizing knowledge and scholars in statu nascendi. Studying closely down to the most subtle details of the activity of the scholars’ hands on the paper of their notes, and with the support of anthropology, history of art, literature, or history of emotions, Simon hopes to flesh out anew a historical epistemology too conceptual and positivist still.
