Elyahou Kapon
Eli Kapon received his Ph.D. in physics from Tel Aviv University, Israel in 1982. He then spent two years at the California Institute of Technology, Pasadena, as a Chaim Weizmann Research Fellow, where he worked mainly on phase-locked arrays of semiconductor lasers. From 1984 till 1993 he was with Bellcore, New Jersey, first as member of technical staff, and from 1989 as District Manager. At Bellcore, he worked on integrated optics in III-V compounds and on low-dimensional semiconductor nanostructures, particularly quantum wires and quantum dots. He managed the Quantum Structures District and the Integrated Optoelectronics District at Bellcore from 1989 till 1992 and from 1992 till 1993, respectively. In 1993 he was appointed Professor of Physics of Nanostructures at the Physics Department of the Swiss Federal Institute of Technology in Lausanne (EPFL), where he heads the Laboratory of Physics of Nanostructures. In 1999-2000 he spent his sabbatical as Sackler Scholar at the Mortimer and Raymond Sackler Institute of Advanced Studies in Tel Aviv University, Israel. During that period he helped establishing the Tel Aviv University Center for Nanoscience and Nanotechnology and served as its first Director from 2000 to 2002. In 2001 he founded the start up BeamExpress and has been serving as its Chief Scientist. He is currently serving as Director of the Institute of Quantum Electronics and Photonics in the Faculty of Basic Sciences at EPFL. His research interests include self-organization of nanostructures, optical properties and electron transport in low-dimensional quantum structures, quantum wire and quantum dot lasers, photonic crystals and vertical cavity surface emitting lasers. He is author or co-author of >300 journal articles, >10 patents, and editor of two books on semiconductor lasers.
Prof. Kapon is Fellow of the Optical Society of America, the Institute of Electrical and Electronics Engineers, and the American Physical Society of America, and a recipient of a 2007 Humboldt Research Award.
Michel Rappaz
After a PhD in solid state physics (1978) at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and a post-doc at Oak Ridge National Laboratory, Michel Rappaz joined the Institute of Materials of EPFL in 1981. After two years in an engineering company, he came back to EPFL in 1984 where he was nominated Adjunct Professor in 1990 and Full Professor in 2003. He retired from EPFL in 2015 and is now Emeritus Professor and independent consultant for several industries and research centres.
His main interests are in phase transformations and solidification, in particular the coupling of macroscopic aspects of heat and mass transfer with microscopic aspects of microstructure and defect formation. Among his diverse achievements, one can mention in particular the development of cellular automata for grain structure predictions and of granular models for hot tearing formation in castings, the coupling of Finite Element method with microscopic models of nucleation and growth, the application of the phase field method to the understanding of various microstructures, the discovery of quasicrystal mediated-nucleation in alloys, and many other studies both fundamental at the microstructure-defect level and more applied at the level of processes.
Some of the software developments have been commercialized by a spin-off company founded by his group in 1991 (Calcom SA), now part of the French company ESI. Michel Rappaz initiated in 1992 an annual postgraduate course on solidification which has been attended by more than 900 participants from all over the world. He is presently collaborating closely with another spin-off company started from his group, Novamet SàrL.
Michel Rappaz has received several awards, in particular the Mathewson co-author award (1994) and author award (1997) of the American Mineral, Metals and Materials Society (TMS), the Koerber foundation award jointly with Profs Y. Bréchet and M. Asbby (1996), the Sainte-Claire Deville Medal (1996) and the Grand Medal (2011) from the French Materials Society, the Bruce Chalmers Award of TMS (2002), the Mc Donald Memorial Lecture award of Canada (2005), the FEMS European Materials Gold Medal (2013) and the Brimacombe Prize of TMS (2015). He is a highly-cited author of ISI, a fellow of ASM, IOP and TMS, and has co-authored more than 200 publications and two books.
Mark Pauly
Mark Pauly is a full professor at the School of Computer and Communication Sciences at EPFL. Prior to joining EPFL, he was assistant professor at the CS department of ETH Zurich since April 2005. From August 2003 to March 2005 he was a postdoctoral scholar at Stanford University, where he also held a position as visiting assistant professor during the summer of 2005. He received his Ph.D. degree (with distinction) in 2003 from ETH Zurich and his M.S. degree (with highest honors) in 1999 from TU Kaiserslautern. His research interests include computer graphics and animation, shape modeling and analysis, geometry processing, architectural geometry, and digital fabrication. He received the ETH medal for outstanding dissertation, was awarded the Eurographics Young Researcher Award in 2006 and the Eurographics Outstanding Technical Contributions Award in 2016.
Tudor Ratiu
Citoyen des Etats-Unis, Tudor Ratiu est né en 1950 à Timisoara, Roumanie. Il a obtenu un diplôme en mathématiques en 1973 ainsi qu'un diplôme de maîtrise en mathématiques appliquées en 1974 à l'Université de Timisoara. Pour des raisons politiques il lui est interdit de poursuivre ses études et en 1975 il est obligé de quitter son pays. En 1980 il obtient un doctorat à l'Université de Californie à Berkeley avec une thèse en mécanique géométrique et est nommé professeur assistant de recherche T.H. Hildebrandt à l'Université de Michigan, Ann Arbor.
En 1983 il rejoint l'Université d'Arizona, Tucson, comme professeur associé et en 1987 l'Université de Californie, Santa Cruz, ou il est nommé professeur ordinaire en 1988. Il lui a été décerné une bourse postdoctorale du Fonds national scientifique américain, une bourse de la fondation A.P. Sloan, la chaire de recherche professoriale Miller à Berkeley, une bourse Fulbright et le prix allemand A. von Humboldt. Il a été professeur et chercheur invité dans plusieurs départements et instituts de recherche mathématiques du monde.
Les thèmes principaux de sa recherche sont l'analyse globale, la mécanique des fluides et du plasma, la dynamique hamiltonienne, la mécanique géométrique, la géométrie symplectique et de Poisson, la théorie de bifurcations et l'étude des systèmes complètement intégrables. Ses travaux concernent l'aspect mathématique de ces problèmes ainsi que leurs applications en physique et les sciences d'ingénieur. Il est auteur, en collaboration, de plusieurs livres de spécialité.
En 1997 il est nommé professeur ordinaire en analyse au Département de mathématiques et entre en fonction en juillet 1998.
