Xianfeng Wang seeks to understand how hydro-climate changes in the tropics during late Pleistocene and Holocene relate to those in other parts of the world, if they are connected at all, and how tropical climate changes influence human society or vice versa. To achieve this, he and his team work with both terrestrial and marine sediment samples from the tropics, including speleothems and corals. Sample ages are typically determined by high precision radiometric dating techniques, while their stable isotopic compositions and elemental ratios are often applied for semi-quantitative climate assessments and correlations. Studies like this help pinpoint the much needed context for predicting future climate change.
His main research interests are:
- Quaternary paleoclimatology
- Radiogenic and stable isotope geochemistry
- Karst geomorphology
