Abstract: The atomic nucleus offers a unique opportunity to study fundamental properties and interactions of neutrinos. The main subjects of interest are the nature of neutrinos (Dirac or Majorana), mass hierarchy, the absolute scale of neutrino masses, and possible additional sterile neutrinos. In this review, recent progress in the field of laboratory measurements of fundamental properties of neutrinos is briefly presented.

Keywords: lepton number violation, Dirac and Majorana neutrinos, neutrino masses and mixing, neutrino oscillations, tritium beta decay, two-neutrino and neutrinoless double beta decay, nuclear matrix elements, axial-vector coupling constant.
