Karen ScrivenerDe nationalité anglaise, Karen Scrivener est née en 1958. Au cours de sa carrière, ses travaux et sa recherche traitaient des domaines suivants: Identification du développement microstucturale pendant l'hydratation du ciment. Elaboration d'une approche multitechnique pour étudier la microstucture des ciments et bétons, avec accent sur la quantification par analyse des images d'électrons retrodiffusés. Caractérisation de l'auréole de transition de la pâte de ciment autour des granulats. Compréhension des processus de dégardation des bétons, en particulier le gonflement lié à la formation de l'éttringite retardée dans les bétons étuvés.
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.

Philippe GilletPhilippe GILLET completed his undergraduate studies in Earth Science at Ecole normale supérieure de la rue dUlm (Paris). In 1983 he obtained a PhD in Geophysics at Université de Paris VII and joined Université de Rennes I as an assistant. Having obtained a State Doctorate in 1988, he became a Professor at this same university, which he left in 1992 to join Ecole normale supérieure de Lyon.
The first part of his research career was devoted to the formation of mountain ranges particularly of the Alps. In parallel, he developed experimental techniques (diamond anvil cells) to recreate the pressure and temperature prevailing deep inside planets in the lab. These experiments aim at understanding what materials make up the unreachable depths of planets in the solar system.
In 1997, Gillet started investigating extraterrestrial matter. He was involved in describing meteorites coming from Mars, the moon or planets which have disappeared today and explaining how these were expelled from their original plant by enormous shocks which propelled them to Earth. He also participated in the NASA Stardust program and contributed to identify comet grains collected from the tail of Comet Wild 2 and brought back to Earth. These grains represent the initial minerals in our solar system and were formed over 4.5 billion years ago. He has also worked on the following subjects:
Interactions between bacteria and minerals.
Solid to glass transition under pressure.
Experimental techniques: laser-heated diamond anvil cell, Raman spectroscopy, X-ray diffraction with synchrotron facilities, electron microscopy.
Philippe Gillet is also active in science and education management. He was the Director of the CNRS Institut National des Sciences de lUnivers (France), the President of the French synchrotron facility SOLEIL and of the French National Research Agency (2007), and the Director of Ecole normale supérieure de Lyon. Before joining EPFL he was the Chief of Staff of the French Minister of Higher Education and Research.
