Pascale JablonkaPascale Jablonka is a French/Swiss astrophysicist who specializes in the area of galaxy evolution. She earned a doctorate in astrophysics from the University Paris 7- Denis Diderot in France. She then held a postdoctoral fellowship at the Headquarter of the European Southern Observatory (ESO, Germany), before obtaining a position at CNRS (France). She is currently Directrice de Recherche at CNRS and on leave of absence from Paris Observatory in the Laboratoire d'astrophysique of EPFL. Pascale Jablonka conducts both observations and numerical simulations to gain insights into the formation and evolution of galaxies. Her research focuses on three main topics : > Understanding the nature of the first stars in the Universe > Infering the driving parameters of the galaxy star formation histories > Deciphering the impact of the environment on galaxy evolution. Her research exploits ground-based and space telescopes as well as high performance computing facilities.
Philippe GilletPhilippe GILLET est entré à lEcole normale supérieure de la rue dUlm (Paris) pour y mener des études en sciences de la Terre. En 1983, il obtient un PhD en géophysique à luniversité de Paris VII et rejoint luniversité de Rennes I comme assistant. En 1988, titulaire dun doctorat dEtat, il devient professeur dans cette même université et la quitte en 1992 pour rejoindre Ecole normale supérieure de Lyon.
La formation des chaînes de montagnes, et des Alpes en particuliers, est lobjet de la première partie de sa carrière scientifique. En parallèle, il développe des techniques expérimentales (cellules à enclumes de diamants)qui permettent de simuler en laboratoire les conditions de pression et de température qui règnent au sein des planètes. Lobjectif de ces expériences est de comprendre de quels matériaux sont constituées les profondeurs inatteignables des planètes du système solaire.
En 1997, il commence à travailler sur la matière extraterrestre. Il participe à la description de météorites venant de Mars, de la Lune ou de planètes aujourdhui disparues et explique comment celles-ci ont été expulsées de leur planète dorigine par des chocs titanesques avant darriver sur Terre. Il a aussi participé au programme STARDUST de la NASA et contribué à lidentification de grains de comète ramenés sur Terre après avoir été capturés au voisinage de la comète Wild-II. Ces grains représentent les premiers minéraux de notre système solaire, formés il y a plus de 4,5 milliards dannées. Il a aussi travaillé sur les sujets suivants :
interactions entre bacteries et minéraux;
amorphisation sous pression;
techniques expérimentales: cellule à enclumes de diamant, spectroscopie Raman,diffraction des RX sur source synchrotron, microscopie électronique.
Philippe Gillet a aussi une activité de management de la science et de lenseignement. Il a ainsi dirigé lInstitut National des Sciences de lUnivers du CNRS (France), présidé le synchrotron français SOLEIL, lAgence Nationale de la Recherche française(2007) et lEcole normale supérieure de Lyon. Avant de rejoindre lEPFL il a été le directeur de cabinet du Ministre français de la Recherche et de lEnseignement Supérieur.

Klaus KernKlaus Kern is Professor of Physics at EPFL and Director and Scientific Member at the Max-Planck-Institute for Solid State Research in Stuttgart, Germany. He also is Honorary Professor at the University of Konstanz, Germany. His present research interests are in nanoscale science, quantum technology and in microscopy at the atomic limits of space and time. He holds a chemistry degree and PhD from the University of Bonn and a honorary doctors degree from the University of Aalborg. After his doctoral studies he was staff scientist at the Research Center Jülich and visiting scientist at Bell Laboratories, Murray Hill before joining the Faculty of EPFL in 1991 and the Max-Planck-Society in 1998. Professor Kern has authored and coauthored close to 700 scientific publications, which have received nearly 60‘000 citations. He has served frequently on advisory committees to universities, professional societies and institutions and has received numerous scientific awards and honors, including the 2008 Gottfried-Wilhelm-Leibniz Prize and the 2016 Van‘t Hoff Prize. Prof. Kern has also educated a large number of leading scientists in nanoscale physics and chemistry. During the past twenty-five years he has supervised one hundred PhD students and sixty postdoctoral fellows. Today, more than fifty of his former students and postdocs hold prominent faculty positions at Universities around the world.
Anders MeibomAnders Meibom obtained his PhD in physics from the University of Southern Denmark in 1997. This was followed by two and a half years of PostDoc work at the Hawaii Institute for Geophysics and Planetology, where he conducted mineralogical studies of primitive chondritic meteorites. From 2000 to 2005, he was Research Associate in the Geological & Environmental Sciences, Stanford University, where he represented Stanford in the USGS-Stanford ion microprobe laboratory. In 2005, he became proifessor at the Muséum National dHistoire Naturelle in Paris. From 2006 to 2011 he was the director of the French national NanoSIMS laboratory. Since January 2012, he is professor at the EPFL in the School of Architecture, Civil and Environmental Engineering (ENAC). From April 2014, he is professor ad personam at the Institute of Earth Sciences, University of Lausanne.
César PulgarinProf. C. Pulgarin is Chemist from Lausanne University, Master in environmental chemistry from Geneva University, Ph D in synthesis bio-inspired of natural substances from Neuchâtel University. During his education he carried out several industrial trainings.
Since March 1989, he has been working at the EPFL where he is leader of the Advanced Oxidation Processes Group (GPAO) active in the development chemical, photochemical, electrochemical, ultrasonic processes, their coupling between them and with biological systems to degrade chemical and microbiological pollutants in water and air. He has an H index of 40 and he is the world most cited author in 1) TiO2 photo-assisted bacterial inactivation in water and 2) Coupling of photochemical and biological processes for pollutant degradation. He has been involved in ten African, South American and European international research projects. He has been Swiss representative in COST program 540.
