I specialize in applying geochemical theories and methods, particularly elemental and isotopic analyses, to study past climate and environmental changes. My research focuses on high-resolution reconstructions of climate variability and the responses of marine carbonates to environmental shifts. One of my key contributions has been developing a high-precision carbonate clumped isotope (Δ47) analysis method. This work has clarified biological effects on Δ47 in biogenic carbonates and uncovered fractionation mechanisms during diagenesis and burial, providing a theoretical foundation for broader Δ47 applications in climate studies. I have also reconstructed high-resolution climate records for the South China Sea and western Pacific during the mid-to-late Holocene. These records help distinguish natural climate variability from anthropogenic influences, offering critical insights into past and present climate trends. Additionally, my research has explored traditional and novel isotopic compositions in coral skeletons as indicators of coral biological activity. This work introduces new perspectives on how corals respond and adapt to environmental changes, contributing to a deeper understanding of coral resilience under future climate scenarios.
