The aim of the Relativistic Heavy Ion Collider (RHIC) program was to discover and quantify the properties of the quark–gluon plasma (QGP). Our experimental results indicated strong collective behavior that was only describable in terms of nearly in viscid hydrodynamics. The results showed that the QGP was the perfect fluid. We also found that the expected suppression of fast partons traversing the medium, referred to as jet quenching. First measurements of non-photonic electrons from the decay of charm and beauty quarks also indicated large modifications in the produced medium. Our results played major roles in drawing a new picture of the QGP. We placed world best limits (2003) on Neutrino Magnetic Moment from the Kuo-Sheng Reactor Neutrino Experiment. A search of axions produced was conducted at the Kuo-Sheng Nuclear Power Station, no evidence of axion emissions were observed and constraints on the couplings ga and gaee versus axion mass ma within the framework of invisible axion models were placed. This experimental approach provided a unique probe for axion mass at the keV-MeV range not accessible to the other techniques. We placed new limits on Spin-independent couplings of low-mass WIMP Dark Matter with Germanium Detector at a threshold of 200eV.

The next generation of 0νββ experiments would cover −IH. In addition, community should be able to explore the strategies and demonstrate sufficient margins to advance towards −NH. A significant merit would be to have no irreducible background before reaching the background index ∼O(10−6) counts/(w1/2-ton-yr) background-free configuration. Detailed studies of this background as well as other channels like those due to residual cosmogenic radioactivity and long-lived radioactive isotopes are themes of our ongoing research efforts.

Measured effective Dynamic Range in measurements with Flash Analog to Digital Converter. Technique developed for the near threshold pulse shape discrimination in scintillating CsI(Tl) Crystals. Suggested possibility of monitoring of unwarranted plutonium production during reactor operation − an issue of paramount importance in the control of nuclear proliferation, using electron-neutrino flux measurement at the nuclear power plants using portable germanium detectors.
