My research interests are mainly focused on understanding the tectonic evolution of orogenic belts and the deformational processes involved in their development, coupled with surface and atmospheric feedbacks. I use a multi-proxy approach to constrain the time and rate of the tectonic exhumation and of the surface erosional process of evolving mountain ranges. I’m also interested in the source to sink sediment evolution and how this can bias the thermochronometric record. My research is deep-rooted and highly dependent upon laboratory analysis, field-based studies, and in collaborating with numerical modelers. My work aims at establishing the spatial and temporal distribution of deformation and erosion at regional and local scales through also the analysis of syn-sedimentary sequences and modern detritus. This geologic framework forms the foundation for my synthesis and interpretation of thermochronological, geomorphic, geochronology (40Ar/39Ar, fission-tracks, U-Th/Pb), and microstructural data. GIS database building is a key part of my research activities and serves as the platform for synthesizing different data. I’m involved in projects in the Himalaya (Nepal, India), Tibet, Alps, Sardinia and Dinarides.
