Pierre Raphaël



  • 2015 : ERC consolidator grant
  • 2014 : Alexandre Joannidès Prize (French Academy of Sciences)


A graduate of the Ecole Polytechnique and the Ponts et Chaussées Engineering school, Dr. Raphaël joined the CNRS in 2004 after completing his Ph.D. in applied mathematics. He became an Assistant Professor at Princeton in 2006, a Professor at the University Paul Sabatier in Toulouse in 2007, and a junior member of the Institut Universitaire de France in 2011. He joined the Jean Alexandre Dieudonné laboratory in September of 2012.

His work addresses the study of wave propagation in non-linear media, for example that of a laser beam in a crystal. One phenomenon that is relevant for physics but which is poorly understood at the mathematical level is the possible concentration of wave energy which can, in certain cases, lead to the formation of singularities. Dr. Raphaël's results have allowed a complete description of this mechanism for certain classical models in mathematical physics, in particular for Schrodinger's equation (a fundamental equation in quantum mechanics). 

His scientific reputation has led to a number of international invitations (Zurich, Princeton, MIT, Berkeley). He was an invited speaker at the International Congress of Mathematicians in 2014 in Seoul, in the joint session on Partial Differential Equations/Mathematical Physics, and in the fall of 2014 he received the Alexandre Joannidès Prize from the Academy of Sciences. Finally, in the spring of 2015 he was awarded a five-year ERC consolidator grant.
