My research activity moves within the scope of the international experiment DUNE (Deep Underground Neutrino Experiment) aimed at the precise measurement of the neutrino flavor oscillation parameters, such as the CP-violating phase in the lepton sector. In particular, I’m involved with the INFN research group in the design and simulation of the SAND detector which will be part of the DUNE Near Detector complex at Fermilab (Illinois, USA). My effort is focused on the development of a new optical readout of the liquid Argon scintillation light for GRAIN, the internal SAND target, which could allow a spatial reconstruction of tracks. I also collaborate in several activities for the ICARUS detector of the SBN (Short Baseline Neutrino) experiment at Fermilab, such as event scanning for neutrino interactions and remote monitoring shifts of the detector status. I also took part in the test and assembly activities of the ICARUS Cosmic Ray Tagger (CRT) system at Laboratori Nazionali di Frascati (LNF) as well as its installation and commissioning on top of the detector at Fermilab.
