Welcome :-)

I am currently (sept. 2010 - aug. 2011) a post-doctoral fellow at the Laboratoire de Mathématiques Jean Leray, Université de Nantes.

Research Activities

My current research activity consists of numerical simulations of integral equations and their application to electrocardiology. It involves Boudary Element Method (BEM) and Fast Multipole Method (FMM) from the Finite Element approach.

Last year, I was involved in the making of numerical multi-level model, based on Domain Decomposition technics, for building's phenomena (radiation coupled with advection-diffusion equations).

My PhD deals with Geometric Integration for Partial Differential Equations (namely "Geometric integrators: Application to Fluid Mechanics", see below). The topic could be summarized as follows: assuming that the physical properties of a system are carried by the geometrical structure of the equations (in sense of the differential geometry), specially in their symmetry group, therefore it is natural to expect from numerical methods to preserve the symmetries of the continuous equations. Surprisingly it is in general not the case for most of standard numerical methods! My aim consisted to propose an algorithmic way of construction of such Lie-symmetry-based integrators, their implementation and the applications to Fluid Mechanics.

Teaching Activities

I have given courses at the University of La Rochelle (from 2005 to 2009) and at the University of Nantes (2010). Most of my courses are related with Numerical Methods, Mathematics and Mechanics.

    Teaching Activities

    Most of my five years teaching activities concerned the Engineering Formation at the third year of BSc degree (Licence L3) and also at the first year of MSc degree (M1). I was involved in Lectures (L), Recitations (R) and Practical Teaching (PT), including grading activities.
