Giorgio MargaritondoDe nationalité américaine et suisse, Giorgio Margaritondo est né à Rome (Italie) en 1946. Il a reçu la Laurea cum laude en physique de l'Université de Rome en 1969. De 1969 à 1978, il a travaillé pour le Consiglio Nazionale delle Ricerche (CNR), à Rome, à Frascati et, pendant la période 1975-1977, chez Bell Laboratories aux Etats-Unis. De 1978 à 1990, il est professeur de physique à l'Université du Wisconsin, à Madison (Etats-Unis); en 1984, il est nommé vice-directeur au Centre de rayonnement synchrotron de la même université. En 1990, il est engagé à l'EPFL comme professeur ordinaire et dirige l'Institut de physique appliquée au Département de physique. Il a été également membre honoraire du corps professoral de l'Université Vanderbilt à Nashville. En 2001 il a été nommé doyen de la Faculté des sciences de base de l'EPFL; en 2004, il a été nommé Vice-président pour les affaires académiques.; en 2010 et jusqu'à sa retraite de l'EPFL en 2016 il est devenu Doyen de la formation continue. A côté de ses cours de physique générale, son activité de recherche porte sur la physique des semiconducteurs et des supraconducteurs (états électroniques, surfaces, interfaces) et des systèmes biologiques; ses principales méthodes expérimentales sont la spectroscopie et la spectromicroscopie électroniques, l'imagerie aux rayons x et la microscopie SNOM, y compris les expériences avec le rayonnement synchrotron et le laser à électrons libres. Auteur d'environ 700 articles scientifiques et de 9 livres, il a aussi été responsable de 1995 à 1998 des programmes scientifiques du Synchrotron ELETTRA à Trieste. Depuis 1997, il a été le coordinateur de la table ronde de la Commission européenne pour le rayonnement synchrotron, et président du conseil de la "Integrated Initiative" de la Commission européenne pour les synchrotrons et les lasers à électrons libres (IA-SFS, ensuite ELISA), le plus grand réseau au monde de laboratoires dans ce domaine. En 2011-2015, il a été Editor-in-Chief du Journal of Physics D (Applied Physics). A présent, il est vice-président du conseil de l'Università della Svizzera Italiana (USI) et président du Scientific and Technological Committee de l'Istituto Italiano di Tecnologia (IIT). Il est "Fellow" de l'American Physical Society et de l'American Vacuum Society; il est également "Fellow and Chartered Physicist" de l'Institute of Physics.
Jan Sickmann HesthavenProf. Hesthaven received an M.Sc. in computational physics from the Technical University of Denmark (DTU) in August 1991. During the studies, the last 6 months of 1989 was spend at JET, the european fusion laboratory in Culham, UK. Following graduation, he was awarded a 3 year fellowship to begin work towards a Ph.D. at Riso National Laboratory in the Department of Optics and Fluid Dynamics. During the 3 years of study, the academic year of 1993-1994 was spend in the Division of Applied Mathematics at Brown University and three 3 months during the summer of 1994 in Department of Mathematics and Statistics at University of New Mexico. In August 1995, he recieved a Ph.D. in Numerical Analysis from the Institute of Mathematical Modelling (DTU). Following graduation in August 1995, he was awarded an NSF Postdoctoral Fellowship in Advanced Scientific Computing and was approinted Visiting Assistant Professor in the Division of Applied Mathematics at Brown University. In December of 1996, he was appointed consultant to the Institute of Computer Applications in Science and Engineering(ICASE) at NASA Langley Research Center (NASA LaRC). As of July 1999, he was appointed Assistant Professor of Applied Mathematics, in September 2000 he was awarded an Alfred P. Sloan Fellowship, as of July 2001 he was awarded a Manning Assistant Professorship, and in March 2002, he was awarded an NSF Career Award. In January 2003, he was promoted to Associate Professor of Applied Mathematics with tenure and in May 2004 he was awarded Philip J. Bray Award for Excellence in Teaching in the Sciences (the highest award given for teaching excellence in all sciences at Brown University). He was promoted to Professor of Applied Mathematics as of July 2005. From October 2006 to June 2013, he was the Founding Director of the Center for Computation and Visualization (CCV) at Brown University. As of October 2007, he holds the (honorary) title of Professor (Adjunct) at the Technical University of Denmark. In November 2009, he successfully defended his dr.techn thesis at the Technical University of Denmark and was rewarded the degree of Doctor Technices -- the highest academic distinction awarded based on ... substantial and lasting contributions that has helped to move the research area forward and penetrated into applications. As grant Co-PI he served from Aug 2010 to June 2013 as Deputy Director of the Institute of Computational and Experimental Research in Mathematics (ICERM), the newest NSF Mathematical Sciences Research Institute. After having spend his entire academic career at Brown University, Prof Hesthaven decided to pursue new challenges and joined the Mathematics Institute of Computational Science and Engineering (MATHICSE) at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland in July 2013. In March 2014 he was elected SIAM Fellow for contributions to high-order methods for partial differential equations.
