My research focuses on the theoretical aspects of cosmology, and on what cosmology can tell about the physics that lies beyond the Standard Model of fundamental interactions. By looking at the sky, indeed, we see many evidences of the existence of a physics beyond the Standard Model. Such physics has to account for the origin of the baryon asymmetry of our Universe, the presence of dark matter, the current and the primordial phases of accelerated expansion of the Universe.
I am mostly interested in the study of primordial inflation, with particular emphasis on models where particle production during inflation can lead to observable signatures in the Cosmic Microwave Background. I am also working on various aspects of the (possible) direct detection of cosmological gravitational waves. More in general, I am interested on the behavior of quantum fields on nontrivial backgrounds.
