BIOGRAPHY
|
Jean-François Molinari is the director of the Computational Solid Mechanics Laboratory (http://lsms.epfl.ch) at the Ecole Polytechnique Fédérale de Lausanne (EPFL, Switzerland). He holds appointments in the institutes of Civil Engineering (http://iic.epfl.ch) and of Materials Science (http://imx.epfl.ch) as well.
He obtained in 2001 a Ph.D. in Aeronautics at the California Institute of Technology (Caltech). He held professorships in several countries including the United States (Mechanical Engineering at the Johns Hopkins University; 2000-2006) and France (Laboratoire de Mécanique et Technologie, ENS Cachan; 2005-2007 and was a Teaching Associate at the Ecole Polytechnique de Paris; 2006-2009. Prof. Molinari holds an Associate Research Professor position at the Johns Hopkins University since 2006.
The numerical work conducted by Prof. Molinari and his collaborators takes place at the frontier between traditional disciplines and ranges from the atomic scale to continuum mechanics. The activities of the laboratory span the domains of damage mechanics of materials and structures, nano- and microstructural mechanical properties, and contact mechanics. There, multiscale modelling techniques are developed and used to understand the origins of friction. Prof. Molinari is a recipient of a 2009 ERC starting grant award.
Jean-François Molinari is closely collaborating with some of the most renowned researchers in Mechanics of Solids and Mechanics of Materials. The activities of the LSMS benefit from strong collaborations with colleagues at EPFL, at the Johns Hopkins University, the MIT, Brown University, the ENS Cachan, and in other European and American universities.

TEACHING
|
Prof. Molinari is involved in teaching at EPFL at bachelor, master and doctoral programme levels.
His teaching programme in Autumn is “Introduction to multiscale methods” (MAS 1+3, OPT), “Modélisation numérique des solides et structures” (BA 4, OPT), “Selected topics in mechanics of Solids” (Fracture mechanics, dynamics), MAS 1+3 OPT).
His Spring class concerns “Mécanique des milieux continus” (BA2 OBL).
At the Doctoral School (EDME) he is teaching “Computational solid mechanics”.
