        Research interests:

        Much of my research efforts revolve around finding novel signatures of physics beyond the Standard Model and to devise strategies to experimentally test them. I deem such work as very important as it creates new perspectives and science cases for existing and future experiments. I am also thrilled by the prospect that a non-gravitational detection of Dark Matter and a conclusive test of the paradigm is a realistic possibility within the next decade. Therefore, I am pushing my research towards the exploration of laboratory tests of Dark Matter.

        The physics of the early Universe, and, in particular, the physics framework of Big Bang Nucleosynthesis are further active lines of my research. I am interested in exploring various generation mechanisms of Dark Matter and to look for cosmological signatures of the hidden sector. Upcoming precision determinations of deuterium and helium abundances, together with the still unsolved cosmological lithium problem keeps primoridal nucleosynthesis a most important window to test for deviations from Standard Model during those first seconds after the big bang.
