I am a cosmologist mostly interested with the physics of the very early Universe mainly through the prism of gravitational wave detectors. My specialities range from the study of topological defects to the aftermath of a first order phase transition and the formation of Primordial Black Holes; but I am always keen to discover new things.

I have been involved in gravitational wave experiments, both ground-based (Virgo) and space-bound (LISA).
