He was Assistant Professor at EPFL (2002-2007), where he is now a Full Professor of Electrical Engineering and, by courtesy, of Computer and Communication Sciences. As of 2015, Prof. Vandergheynst serves as EPFL’s Vice-Provost for Education. His research focuses on harmonic analysis, sparse approximations and mathematical data processing in general with applications covering signal, image and high dimensional data processing, computer vision, machine learning, data science and graph-based data processing. He was co-Editor-in-Chief of Signal Processing (2002-2006), Associate Editor of the IEEE Transactions on Signal Processing (2007-2011), the flagship journal of the signal processing community and currently serves as Associate Editor of Computer Vision and Image Understanding and SIAM Imaging Sciences. He has been on the Technical Committee of various conferences, serves on the steering committee of the SPARS workshop and was co-General Chairman of the EUSIPCO 2008 conference. Pierre Vandergheynst is the author or co-author of more than 70 journal papers, one monograph and several book chapters. He has received two IEEE best paper awards.

Michel Deville
Michel Deville est né le 26 février 1945 à Charleroi (Belgique). Ingénieur civil électricien-mécanicien de l'Université Catholique de Louvain (1968), il y a présenté sa thèse de doctorat en sciences appliquées en 1974. Le sujet en était l'intégration numérique des équations de Navier-Stokes par la méthode des différences finies.
En 1974-1975, il séjourne en tant que boursier OTAN au Département de mathématiques du MIT chez le Prof. S.A. Orszag. A cette occasion, il se familiarise avec les méthodes spectrales pour le calcul des écoulements de fluides incompressibles. Ensuite, sa carrière académique se déroule à l'Université de Louvain: chargé de cours, professeur, professeur ordinaire.
Depuis 1979, il est collaborateur à la division d'aérodynamique de l'ONERA (Chatillon, France). Il est spécialiste des méthodes spectrales. Il applique les méthodes numériques à la simulation directe d'écoulement des fluides, à la modélisation de la turbulence et au calcul des fluides non-Newtoniens. Il est nommé professeur à l'EPFL le 1er septembre 1993, où il conduit les travaux liés à la mécanique des fluides numériques.Il prend sa retraite le 28 février 2010. Il est actuellement rédacteur en chef de la revue Computers and Fluids.
Giorgio Margaritondo
Citizen of the USA and Switzerland, Giorgio Margaritondo was born in Rome, Italy, in 1946. He received the Laurea summa cum laude from the University of Rome in 1969. From 1969 he was an employee of the Italian National Research Council in Rome and Frascati and, in 1975-77, he was at Bell Laboratories in the USA. From 1978 to 1990, he was professor of physics at the University of Wisconsin-Madison in the USA; in 1984 he was nominated associate director for research of the Synchrotron Radiation Center of the same university. In 1990 he was nominated "professeur ordinaire" (full professor) at the EPFL; he directed the Institute of Applied Physics and the Physics Department. He was also a honorary faculty member at Vanderbilt University in Nashville. In 2001 he became Dean of the EPFL Faculty of Basic Sciences. In 2004 he was nominated Provost and he served until 2010, when he became Dean of Continuing Education, until his retirement from the EPFL in 2016 In addition to teaching general physics, his activity concerns the physics of semiconductors and superconductors (electronic states, surfaces and interfaces) and of biological systems; his main experimental techniques are electron spectroscopy and spectromicroscopy, x-ray imaging and scanning near-field microscopy, including experiments with synchrotron light and with free electron lasers. Author of more than 700 scientific publications and 9 books, he was also coordinator in 1995-98 of the scientific division of the Elettra synchrotron in Trieste. In 1997-2003 he was coordinator of the European Commission Round Table on synchrotron radiation, and then became president of the Council of the European Commission Integrated Initiative on Synchrotron and Free Electron Laser Science (IA-SFS and then ELISA), the largest network in the world in this domain. In 2011-15, he was Editor-in-Chief of Journal of Physics D (Applied Physics). He is currently vice-president of the council of the Università della Svizzera Italiana (USI), and president of the Scientific and Technological Committee of the Italian Institute of Technology (IIT). He is Fellow of the American Physical Society and of the American Vacuum Society and Fellow and Chartered Physicist of the Institute of Physics.
Marco Grioni
Marco Grioni was born in Milan (Italy) where he graduated in 1982. He has occupied research positions at Minneapolis (USA), Nijmegen (The Netherlands), Orsay (France) and Neuchâtel, where he became Privat Docent in Solid State Physics in 1994.

His research interests concern the electronic properties of novel materials,namely high-temperature superconductors, low-dimensional metals, and heavy fermion compounds, which he investigates by high-resolution photoemission (ARPES), ultrafast time-resolved ARPES, and photon-in photon-out synchrotron-based spectroscopies. Author of approx. 220 scientific articles, he is actively involved in the development of new instruments. From 2003 to 2006 he was the chairman of the users organization of the European Synchrotron Radiation Facility (ESRF Grenoble). Between 2010 and 2017 he served as chairman of the scientific advisory committee of the french national synchrotron light source SOLEIL
François Gallaire
Né le 26 février 1975, François Gallaire obtient, en 1998, le diplôme dingénieur de lEcole Polytechnique à Paris et, en 1999, un master en « Physique des liquides » à lUniversité Pierre et Marie Curie, toujours à Paris. Il rejoint ensuite le Laboratoire dhydrodynamique (LadHyX) à lEcole polytechnique où il soutient, en 2003, une thèse sur le thème des instabilités des jets tournants et sur le contrôle de léclatement tourbillonnaire sous la direction de Jean-Marrc Chomaz. En 2003, il est nommé chargé de recherche au CNRS au Laboratoire J.A. Dieudonné de lUniversité de Nice Sophia-Antipolis.En 2009, il rejoint l'EPFL pour y fonder le laboratoire des mécanique des fluides et instabilités (LFMI). Ses recherches se concentrent sur létude des propriétés fondamentales de stabilité des écoulements de fluides et sont guidées par les applications réelles, en particulier le contrôle des écoulements. Récemment, il a réalisé dimportantes contributions dans les domaines de la micro-fluidique (lanalyse de la manipulation par laser dune goutte dans un micro-canal) et la dynamique des bio-fluides (le descriptif mécanique de lanévrisme de laorte abdominale).
