The NDM symposia are designed to bring together researchers in the fields of neutrino physics, astrophysics, dark-matter physics, and nuclear-structure physics to discuss the theory and experimental developments needed to investigate neutrinos and dark matter with nuclear targets or decay, astrophysical phenomena, etc. With the growing role of astrophysics and low-energy experiments in fundamental physics, the NDM symposia are an increasingly important way to exchange ideas and results among people from different areas. No other large meetings address, for example, the role of nuclear structure in fundamental physics.
