We have applied elemental and isotopic fingerprints of biogenic and inorganic carbonates, such as corals, foraminifera, speleothem, to modern and past climatic and environmental changes using state-of-art analytical techniques. Applied interdisciplinary fields include high-precision U-Th geochronology, high-resolution records of climate, environment, vegetation, and anthropogenic pollution, and issues involving paleoclimate change, oceanography, paleoceanography, and anthropology. We have developed geo-analytical techniques, including high-precision Sr/Ca ratio TIMS, high-precision U-Th analysis by MC-ICP-MS and SF-ICP-MS, and high precision determinations of Mg/Ca, Sr/Ca, and rare earth elements/Ca by SF-ICP-MS. Since 2001, we have participated in over 40 domestic and international projects in Taiwan ROC, USA, Japan, Vietnam, Philippines, Hungary, Singapore, and Mainland China.
