Currently, among other activities, I participate with ICN colleagues in the DAMIC and CONNIE experiments, which use scientific-grade CCD devices as particle detectors. DAMIC (Dark Matter In CCDs), installed in the SNOLAB underground laboratory in Canada, searches for different candidates for light dark matter, and CONNIE (Coherent Neutrino Nucleus Interaction Experiment) seeks to detect the coherent elastic scattering of neutrinos by nuclei using antineutrinos from a nuclear reactor (Angra 2, Brazil).
