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.
In the Fall semester, he is teaching "Continuum Mechanics" (BA 3), and "Selected Topics in Mechanics of Solids and Structures" (MAS 1+3, OPT), which includes an introduction to Wave Dynamics and to Fracture Mechanics. This Master class is taught in alternate years with Advances in Computational Solid Mechanics (MAS 1+3, OPT).
In the Spring semester, Prof. Molinari is teaching "Finite-Element Method" (BA 6).
