Germanium detectors with sub-keV sensitivities offer a unique opportunity to study neutrino interactions and properties, as well as search for light WIMP Dark Matter. The TEXONO Collaboration has been pursuing research program on low energy neutrino interactions and light WIMP Dark Matter at the Kuo-Sheng Neutrino Laboratory (KSNL) in Taiwan and China Jinping Underground Laboratory (CJPL) in China. We will present highlights of physics program on the studies of neutrino electromagnetic interactions [1,2] as well as neutrino-nucleus coherent elastic scattering [3,4]. We will highlights of the detector characterization and performance [5] and also report the upper limits on both spin-independent and spin-dependent WIMP-nucleon interaction cross-section with an point-contact germanium detector [6.7].
