Short bio

I was born in 1995 in Toulouse (France) . After spending 20 years within a one-kilometre radius around my house with both highschool and CPGE in Lycée Pierre de Fermat (Toulouse, France), I entered the Ecole Normale Supérieure Paris-Saclay (formerly ENS Cachan) in 2015 in the departement of Physics. After various internships on electromagnetics, modelisation and numerical methods in France, New Zealand and Danemark. I am now doing a joint PhD between the GeePs (Paris, France) and the departement of Energy "Galileo Ferraris" from Politecnico di Torino (Turin, Italy), supervised by Lionel Pichon and Fabio Freschi. For more details, here is my CV.

Research work

My work is currently focusing on high power inductive power transfer systems(IPT) in general. Due to the variability of many geometrical or physical parameters in these systems, their numerical models are extremely complex. Thus, one cannot simply use a FEM model or conduct numerous experiments to perform an accurate sensitivity analysis for example, as it would take too much computation time. Hence why, I introduced a useful combination of surrogate models (metamodels) with the complex model in order to build accurate predictors at a low computation cost. The predictor can then be used in lieu of the real model for various computations such as sensitivity analysis or optimization processes.

In order to build an accurate predictor for various systems, I developed an adaptive algorithm using fewer samples than classical methods which builds a training dataset sequentially focusing on the regions where the uncertainty is the greatest. The resulting metamodel is based on a combination of Kriging and polynomial chaos expansion surrogate models. This predictor is an analytical function which can be computed at instant speed and allows fast and reliable sensitivity analysis. The accurate predictor can also be used instead of the estimated output model for optimization algorithm when building new designs.

My work is particularly focusing on the assessment of human exposure around high power IPT systems. With the extreme complexity of current 3D human models, metamodelling processes can be particularly useful for estimating the induced field values in the human body in the vicinity of IPT systems. A dosimetric methodology has been developed to compute easily safety areas around IPT systems according to the current standard and guidelines on electromagentic fields. In particular the case of a numerical model for a standardized WPT system has been analyzed along with some measurements on a real WPT system. The case of a mid-frequency direct current welding gun, needier of exposure assessement, has been also tackled with metamodelling on the response to pulsed magnetic fields.
