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.

Yves Weinand
Biography
Architect and civil engineer, Prof. Dr. Yves Weinand is one of the most recognised researchers in the field of contemporary wood construction. Founder of the Bureau d'Etude Weinand, he has, since 1996, designed and worked on many emblematic wooden buildings, such as the Saint Loup Chapel, the new Vaudois Parliament or, more recently, the Timber Pavilion of Vidy in Lausanne. His fundamental research questions the technical and static possibilities of wooden materials. The interdisciplinary exploration carried out at the EPFL's Laboratory for Timber Constructions (Ibois), of which he is director, concerns wood in all its aspects, from round wood to manufactured wood. The recent research carried out at Ibois on free structures with wood-wood connections (without screw nor glue) has been the subject of several technological transfers, and stands as tangible proof of new possibilities for wood construction. Yves Weinand is currently working on a large-scale project for a hall for the head office of a joinery in Luxembourg, consisting of a succession of arches with spans of 22.5 to 53.7m, entirely assembled in wood ). Through new innovative approaches, the ambition of his research is to develop a new generation of renewable and ecological wooden construction.He is regularly invited to present his work at international symposia on timber construction.
