I am a structural geology researcher interested in orogen evolution. I have so far dedicated most of my works to some Mediterranean chains, e.g. Apennines, Corsica, Cycladic Islands, Helvetic Alps working in the lab and in the field. Between 2013 and 2015 I was Postdoc at the Orléans University (France). In 2013, I've got my PhD at the Swiss Federal Institute of Technology ETH-Zürich. My undergraduate studies were at the Sapienza University (Rome, IT) where I had my MSc in 2008 my BSc in 2006.
Supervisors: Neil S. Mancktelow, Carlo Doglioni, Daniel Bernoulli, and Laurent Jolivet

The island represents the only remaining part of the internal Apennine chains that have been extremely stretched and disrupted due to post-Apenninic extension during Pliocene and Pleistocene. This work aims to establish the relationship between the magnetic fabric and the different tectonic phases. Anisotropy of magnetic susceptibility (AMS) has been measured on 142 oriented specimens collected from 19 sites, representing the Paleozoic meta-sandstones, Late Triassic dolomites, Cretaceous to Eocene Scaglia Rossa limestones, Miocenic flysch and the overlying Messinian gypsy marls. Further, discordant trachytic lavas have been sampled. The upper part of Dolomia Principale, Maiolica, Messinian marls and Quarternary lavas show mainly isotropic f...

Despite the well-studied P-T-t patterns of individual nappes, their relative timing, mode and kinematics of exhuma-tion are debated. In this study, in the frame of the Mediterranean syn-and post-orogenic deformation, examples of shear zone hierarchization and strain localization from Sifnos and Syros islands (Cyclades, Greece) are documented in detail in order to explain 3D-geometries and regional kinematics and are here tentatively related to the Ar/Ar ages available in literature. During the Eocene syn-orogenic uplift, the degree of strain localization increases progressively from blue-to green-schists deformation. Some of these shear zones where then reworked during the Oligo-Miocene post-orogenic deformation in different, usually warmer P-T conditions and a new ...

This area shows the evolution of a fault system from partially ductile to brittle conditions and is currently one of the most seimogenically active zones in Switzerland. This field study aims to establish which fault sets have been activated during the Neogene and possibly Quaternary to Recent, to better constrain their relative age and kinematics, and to study the transition from ductile to brittle behaviour. The observed faults can be assigned to three general sets on the basis of their strike orientation. The first set (1) strikes NE-SW. Faults with distinctly different ages of initial activity are part of this set: Cretaceous normal faults with syn-sedimentary features; thrusts due to nappe-stacking; and later normal to oblique faults. All of these faults dip mainly to the SE. Paleo-tectonic f...

The Wildhorn nappe includes a late Cretaceous succession bearing clear evidence for post-breakup extensional tectonics such as: synsedimentary geometries related to well oriented, parallel and spaced NE-striking faults; sedimentary dykes; lateral variations in the thickness and facies of formations; anomalous and discordant contacts corresponding to paleoescarpments; and slump folds. This field evidence indicates an important Late Cretaceous extensional tectonic event that affects the older Jurassic passive margin sequence. This process cannot be related to partial or local gravitational collapse, being the faults cross-cut suitable candidates for preferential gliding (e.g. the thick succession of Lower Cr...

In this note we address the fault zone development and deformation mechanisms that occur in carbonate lithologies at different crustal levels. We compare faults exhumed near the brittle-ductile transition in the Helvetic Nappes in theAlps and similar faults from the upper crust in the Gran Sasso area in the Central Appenines. We observe the different role of deformation processes at different depth and lithology and assess the tendency for localization at the Brittle Ductile Transition.
