American theoretical nuclear physicist and astrophysicist, engaged in nuclear astrophysics (supernovae, the solar neutrino problem, nucleosynthesis), neutrino physics (neutrino oscillations, neutrinoless double beta decay, neutrino properties), many-body theory (effective theories) in nuclear physics (as well as in atomic physics and condensed matter physics), and tests of symmetries of fundamental interactions (parity, CP-symmetry, lepton number).
