This article reviews the research program and efforts for the TEXONO Collaboration on neutrino and astro-particle physics. The ``flagship program is on reactor-based neutrino physics at the Kuo-Sheng (KS) Power Plant in Taiwan. A limit on the neutrino magnetic moment of $munuebar < 1.3 X 10^{-10} mub}$ at 90% confidence level was derived from measurements with a high purity germanium detector. Other physics topics at KS, as well as the various R&D program, are discussed
