Applied numerical analysis, digital image processing

English : these works are mainly concerned by applied numerical analysis to signal and image processing problems occuring in physical chemistry.

Français : Mes travaux dans le domaine de l’informatique concernent principalement le développement et l’implémentation de méthodes d’analyse numérique, de traitement du signal, de l’image en vue d’applications en chimie-physique (modélisation, simulation, traitement de données expérimentales).
