I did my PhD at the Theoretical Physics Center in Marseille (CPT) and a postdoc at the Mathematics Department in Genoa (DIMA).
I am mainly active in fields related to the application of noncommutative geometry to theoretical physics, in particular concerning
-Noncommutative and pseudo-Riemannian geometries.
-Noncommutative Standard Model, Grand Unified Theories and approximately finite algebras.
-Twisted spectral triples and torsion.
