Research topics

My research activity is centered on the modelling and numerical analysis of linear wave propagation phenomena, in the context of frequency domain electromagnetics and acoustics. My main interests concern:

I have just started, as a leading coordinator, the research project NonlocalDD funded by the French National Research Agency (so-called ANR) for investigating boundary integral equations in conjunction with domain decomposition.

I have also been involved in the METAMATH project funded by the French Research National Agency (abreviated ANR) that focuses on the modelling and numerical analysis of metamaterials. Below are three presentations that provide a glimpse at my research concerns

Boundary element library

For practical purposes (implementation of multi-trace formulations in particular), I am developping my own personal boundary element library. Although far from optimal, with ongoing development, it allows easy/fast implementation of multi-trace formulations. It is called bemtool and is available on GitHub, distributed under the GNU Lesser General Public License.


I am currently involved in the organisation of the following workshops and conference that you are kindly invited to attend
