From the menu on this page, you will be able to access to my detailled CV, to the E.N.S.T.A. Applied Mathematics Unit’s Parallel Computation Pole homepage, and to a page dedicated to some scientific tutorials or guides I wrote on mathematical softwares or programmation languages I was bound to use during my PhD work.

Now, I am going to quickly present my research and teaching activities.

Research activities

2004 - 2009

Phd studies of Doctoral School of Ecole Polytechnique - Funds from the Ministry of Education and Research

Title : Multi-Scale gravitational Dynamics : formation and evolution of a selfgravitating system in an external field.
Supervisors : Marc Lenoir and Jérôme Perez (U.M.A / E.N.S.T.A.)

Development of an intensive computation algorithm (to see the parallel computation machine 's characteristics, please go to the Parallel Computation Pole (PCP) web page) adapted to gravitation and to the multiscale characteristic of the considered systems. The aim is to study the evolution of systems such as a globular cluster in its host galaxy, and more specifically the orbital evolution’s influence on the dynamical and structural properties of N-bodies systems resulting from the gravitational collapse process.
