Expertise

High Performance Computing
Finite Element

Current work

My current work at LSMS is to develop a open source finite element library, called Akantu.
Aside of this general development I work on integral regularization methods for continuum damage laws.
I graduated as an engineer in computer science in 2005 at the Ecole National Superieur en Electronique Informatique et Radiocomunication de Bordeaux (ENSEIRB). My degree is colored by an option od High Performance Computing (HPC).
Then I made my thesis at LaBRI/INRIA Bordeaux in the ScalApplix/HiePACS team, on the in-situ steering of coupled parallel numerical simulations.
I graduated as a Ph D. of computer science of the Universite de Bordeaux 1 in 2010.
Since then I am working at EPFL in the Laboratoire de Simulations en Mechanique des Solides (LSMS) as a scientific collaborator.
