Esther AmstadEsther Amstad studied material science at ETH in Zurich. She also carried out her PhD thesis at the same University under the supervision of Prof. Marcus Textor; for her thesis, she worked on the surface modification and steric stabilization of oxide nanoparticles. As a postdoctoral fellow, she joined the experimental condensed soft matter group of David A. Weitz at Harvard University where she used droplet based microfluidics to assemble different types of functional micro- and nanomaterials. In addition, she developped new microfluidic devices that enable the production of very small, airborne drops as well as devices that produce highly monodisperse emulsion drops at a very high throughput. In June 2014, Esther joined the material science department (IMX) of EPFL where she is leading the Soft Materials Laboratory (SMAL).
Philippe BuffatBorn in Lausanne (Switzerland) in 1942. EPUL physics engineer diploma in 1967 and EPFL PhD in physics in 1976. From 1966 he studies at the Experimental Physics Laboratory (Prof. J.P. Borel) the physical properties peculiar to the very small size metal crystals and gets a PhD degree for his thesis "Abaissement de la température de fusion de petits cristaux d'or par effet de taille thermodynamique" (Lowering of the melting temperature of small gold crystals by thermodynamic size effect). In 1971, he starts to develop an electron microscopy facility available to all EPFL students and researchers (nowadays Centre Interdisciplinaire de Microscopie Electronique CIME) that he manages till 2007. In parallel he teaches the principles of electron microscopy and the Experimental methods of physics at the Physics/Basic Sciences School (SB). In addition, he trains a large part of the facility users. Honorary professor BS/EPFL he carries-out a free-lance research at CIME and in collaboration with the Institute of Crystallography of the Russian Academy of Sciences (ICRAS, Moscow) and the International Centre of Electron Microscopy for Material Science (IC-EM AGH Krakow) This activity covers all the techniques related to transmission and scanning electron microscopy applied to materials science and solid-state physics. His interest is directed towards the structure of nanocrystals, their size effects and behavior under strong electron irradiation, the phase transitions in perovskites, the characterization of nanophases, multilayer and interface structures of crystalline materials and bioceramics. More recently a large research part has moved to understanding/pointing-out the adequacy between the limits of the instruments and their interpretation means in regard of their use in a multiusers facility with a large turnover and a wide range of materials/structures. He is past-president (2006-2007) of the Société Française des Microscopies (Sfµ), honorary member of the Sfµ and of the Swiss Society of Optics and Microscopy (SSOM).
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.

Nava SetterNava Setter completed MSc in Civil Engineering in the Technion (Israel) and PhD in Solid State Science in Penn. State University (USA) (1980). After post-doctoral work at the Universities of Oxford (UK) and Geneva (Switzerland), she joined an R&D institute in Haifa (Israel) where she became the head of the Electronic Ceramics Lab (1988). She began her affiliation with EPFL in 1989 as the Director of the Ceramics Laboratory, becoming Full Professor of Materials Science and Engineering in 1992. She had been Head of the Materials Department in the past and more recently has served as the Director of the Doctoral School for Materials.
Research at the Ceramics Laboratory, which Nava Setter directs, concerns the science and technology of functional ceramics focusing on piezoelectric and related materials: ferroelectrics, dielectrics, pyroelectrics and also ferromagnetics. The work includes fundamental and applied research and covers the various scales from the atoms to the final devices. Emphasis is given to micro- and nano-fabrication technology with ceramics and coupled theoretical and experimental studies of the functioning of ferroelectrics.
Her own research interests include ferroelectrics and piezoelectrics: in particular the effects of interfaces, finite-size and domain-wall phenomena, as well as structure-property relations and the pursuit of new applications. The leading thread in her work over the years has been the demonstration of how basic or fundamental concepts in materials - particularly ferroelectrics - can be utilized in a new way and/or in new types of devices. She has published over 450 scientific and technical papers.
Nava Setter is a Fellow of the Swiss Academy of Technical Sciences, the Institute of Electrical and Electronic Engineers (IEEE), and the World Academy of Ceramics. Among the awards she received are the Swiss-Korea Research Award, the ISIF outstanding achievement award, and the Ferroelectrics-IEEE recognition award. In 2010 her research was recognized by the European Union by the award of an ERC Advanced Investigator Grant. Recently she received the IEEE-UFFC Achievement Award (2011),the W.R. Buessem Award(2011), the Robert S. Sosman Award Lecture (American Ceramics Society) (2013), and the American Vacuum Society Recognition for Excellence in Leadership (2013).
