Research

My PhD project aimed to quantify the different phases of post rift reactivation in SE Brazil using low temperature thermochronometry (Fission Track and (U-Th)/He on apatite) in order to reconcile these phases with the structural history of the region and to identify the causes of post rift reactivation in accordance with both the offshore and onshore data. I am currently working on the evolution of the Irish margin, using apatite fission-track and U-Th/He. More broadly I am interested by the evolution of passive margins, from rifting to the post rift development.I am now also involved in provenance studies in the foreland basins of Western Alps and in the Tethyan sediments of the north Indian margin, to infer the evolution of active mountain ranges. Beside my research work I also undertook some consulting studies for oil companies to infer evolution of basins, and thus potential oil fields, with apatite fission track analyses on wells samples.
