My research activity concerns the study of rare processes in the field of astroparticle physics and using highly radiopure crystal scintillators with experimental activities conducted in underground laboratories such as the Gran Sasso National Laboratories (LNGS). I am member of the DAMA collaboration and my supervisor is Pierluigi Belli. 

During my master thesis work, I contributed to the data taking and data analysis of an experiment for the study of double beta decay modes in 106Cd using a radiopure crystal scintillator in CdWO4 (215.4 g) enriched to 66% in 106Cd which exploits a logic of coincidence with two other radiopure crystal scintillators of CdWO4. The apparatus is being measured at the Gran Sasso National Laboratories (LNGS) of the INFN, in the intrinsic low background experimental set-up called DAMA/R&D.

Furthermore, I was involved in realizing an experiment to characterize two radiopure crystal scintillators in Cs2ZrCl6 and to study double beta decays in Zr isotopes. In particular, I am engaged both in data taking and in their analysis. Moreover, I am involved in the implementation of new experimental apparatuses for the study of rare processes using new generation crystal scintillators. For example, I am also involved in the characterization and implementation of ZnWO4crystals in order to optimize their radiopurification, as well as their optical properties, and possibly increase the light-yield of the scintillator. The aim is to evaluate the use of ZnWO4 scintillator crystals with anisotropic response to study of directionality for those candidates of Dark Matter particles that can induce nuclear recoils.
