Thèmes de recherche
Mes intérêts de recherche actuelles portent sur le traitement du signal et la reconnaissance des formes afin de caractériser des anciens materiaux et systèmes techniques; mes activités de recherche, qui visent à caractériser les techniques de montage des poteries néolithiques en modélisant la distribution des pores et des inclusions à différentes échelles, sont intégrées au projet “TOMAT - Multiscale Tomography: Imaging and Modelling Ancient Materials, Technical Traditions and Transfers” (dans le cadre du programme UCAJEDI “Matière, Lumière, Interactions”, direction Didier Binder).
L’objet principal de mon doctorat a été l’analyse de techniques d’accélération pour des méthodes du premier ordre dans le domaine de l’optimisation nonlinéaire sous contraintes, ainsi que leur impact dans des problèmes de reconstruction du signal pour des applications biomédicales.
Mon travail de thèse de Master a concerné la modélisation et l’émulation avec logiels des nonlinéarités des systèmes audio via un modèle de série de Volterra modifiée.

My present research interests deal with signal processing and shape recognition in order to characterise ancient technical systems and materials; my research activities, whose aim is to characterise manufacturing techniques of Neolithic pottery by multiscale modelling of pores and inclusions distribution, are involved in project “TOMAT - Multiscale Tomography: Imaging and Modelling Ancient Materials, Technical Traditions and Transfers” (direction Didier Binder).
The principal object of my PhD course research was the analysis of acceleration techniques for first–order methods in nonlinear constrained optimization and their impact in signal reconstruction problems arising in biomedical domains.
My Master’s thesis work
concerned the modelling and emulation of nonlinearities of audio systems by means of a modified Volterra series.
