My work focuses on the analysis of vertical movements along active margins to better understand the link between deep geodynamic mechanisms, deformation, and erosion processes. In order to constrain the timing and magnitude of exhumation and thus solve tectonic problems, I am combining diverse methodologies such as fieldwork and seismic analysis with medium- and low-temperature thermochronology, mostly, inverse modelling (to extract time-temperature histories), geochronology and geochemistry (trace elements, Hf and O isotopes) on in-situ and detrital material. Early work focused on the Peruvian forearc basin, Patagonian Cordillera, intraplate belt, and foreland basin (Chile, Argentina). Ongoing research includes investigations on the Ecuadorian Cordilleras and intermountain basins, the Himalaya (India, Nepal), and south-central Mongolia.
