My work is about Riemannian Geometry in its broadest meaning and with interactions with other branches of geometry such as: topology of manifolds and singular spaces, dynamics, global analysis, metric geometry and geometric group theory.

During the years, I have become interested in :

Einstein manifolds and other special structures (symmetric spaces, asymptotically harmonic manifolds etc.),

geometric structures in dimension 3 (hyperbolic, Heisenberg and Sol geometries, non-geometric manifolds etc.)

some topological and differential invariants of manifolds related to systolic geometry and minimizing problems in Riemannian geometry (simplicial volume and bounded cohomology, minimal volume and minimal entropy, Seiberg-Witten invariants etc.)

topological and geometric rigidity (moduli space of special Riemannian structures, convergence theory in Riemannian geometry, pinching, collapsing and finiteness problems)

geometry and dynamics of negatively curved manifolds (counting geodesics, entropy, quasi-conformal measures, ergodicity etc.)

geometry of CAT(0) and Gromov-hyperbolic spaces

geometric group theory (problems related to growth, splittings etc.)

I am also interested in scientific dissemination: I have long been involved in mathematics competitions, I translated the Topologicon of J.P. Petit and I partecipated to many popular science events and meetings (Caffè Scienza, Caffè Matematici, Scienza 3, La Scienza a Scuola etc.).
