- 1994 - Degree in Earth Sciences (University of Pisa) with a thesis entitled "Geology of the ophiolitic units in the Urtier Valley, Cogne - Western Alps".
- 1995-1999 - PhD in Earth Sciences entitled "Pre-oligocenic structural evolution of the Internal Liguride Units units between Polcevera and Scrivia Valleys (Northern Apennines)”.
- 2002-2005 - CNR Research grant entitled "Structural analysis of the Liguride Units of the Northern Apennines finalized to the reconstruction of the post-collisional evolution of the Alps-Apennines system”.
- CNR Researcher since 2006.
- The main research activity is represented by the study of the issues related to the reconstruction of the structural evolution of orogenic belts, with particular interest in the analysis of the transpressive component of the deformation regime in collisional settings. Researches are performed in the Northern Apennines and Western Alps, with special attention to the relationships between Alps and Apennines systems, and in other countries as Morocco and Turkey. These issues are studied by means the structural analysis of geological structures at the mesoscale, including fault, fold and fabric geometries, combined with geological mapping of the geological setting. These methodologies of structural geology and geological mapping are also applied to relevant environmental issues in the framework of projects financed by Tuscany Region and LaMMA Regional Consortium.
- Since 2008 he is the scientific coordinator for IGG of the applied research projects financed by Tuscany Region and LaMMA Regional Consortium. In this context, he is the scientific responsible of two temporary researchers.
- From 2003 to 2011 he was responsible for the geological mapping of the sheet n.261 “Lucca” for the national project for the realization of the Italian Geological Map at the 1:50.000 scale (CARG Project).
