I’m a geologist and geochronologist born and raised between the Apennines and the Alps. My research focuses on quantitatively understanding the tectonic evolution of orogenic belts looking at source rocks and erosional records. I investigate continental collision and feedback loop processes between tectonics, erosion, and climate. My research is deep-rooted upon laboratory analysis, field-based studies, and in collaborating with numerical modelers. I’m involved in projects in the Himalaya (Nepal, India), Tibet and China, Alps, Sardinia, and Dinarides.
