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.

Brice Tanguy Alphonse Lecampion

I am currently an assistant Professor and the head of the Geo-Energy Lab - Gaznat Chair on GeoEnergy at Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland. Prior to joining EPFL, I have worked for Schlumberger in research and development from 2006 until May 2015 - serving in a variety of roles ranging from project manager to principal scientist in both Europe and the United States. I received my PhD in mechanics from Ecole Polytechnique, France in 2002 and worked as a research scientist in the hydraulic fracturing research group of CSIRO division of Petroleum resources (Melbourne, Australia) from 2003 to 2006. During my time in Schlumberger R&D, I have worked on problems related to the integrity of deep wells, large scale monitoring of reservoir deformation and more specifically on the stimulation of oil and gas wells by hydraulic fracturing. My current research interests cover hydraulic fracture mechanics, mechanics of porous media and dense suspensions flow.

Jean-François Molinari

Professor J.F. Molinari is the director of the Computational Solid Mechanics Laboratory (http://lsms.epfl.ch) at EPFL, Switzerland. He holds an appointment in the Civil Engineering institute, which he directed from 2013 to 2017, and a joint appointment in the Materials Science institute. He started his tenure at EPFL in 2007, and was promoted to Full Professor in 2012. He is currently an elected member of the Research Council of the Swiss National Science Foundation in Division 2 (Mathematics, Natural and Engineering Sciences), and co editor in chief of the journal Mechanics of Materials. J.F. Molinari graduated from Caltech, USA, in 2001, with a M.S. and Ph.D. in Aeronautics. He held professorships in several countries besides Switzerland, including the United States with a position in Mechanical Engineering at the Johns Hopkins University (2000-2006), and France at Ecole Normale Supérieure Cachan in Mechanics (2005-2007), as well as a Teaching Associate position at the Ecole Polytechnique de Paris (2006-2009). The work conducted by Prof. Molinari and his collaborators takes place at the frontier between traditional disciplines and covers several length scales from atomistic to macroscopic scales. Over the years, Professor Molinari and his group have been developing novel multiscale approaches for a seamless coupling across scales. The activities of the laboratory span the domains of damage mechanics of materials and structures, nano- and microstructural mechanical properties, and tribology.
