Thèmes de recherche

J'utilise la sismique réflexion, sismique grand angle, gravimétrie magnétisme et sismologie pour comprendre la formation des marges continentales, leur segmentation jusqu'à la mise en place d'une dorsale océanique et la reprise en compression de ces marges, notamment dans un système de failles transformante en domaine de compression hyper-oblique (Haiti).
