This research group is primarily interested in the application of stable and radiogenic isotopes in conjunction with organic and inorganic geochemical approaches to understand bio- and geo-chemical processes, geochronology and physico-chemical records. Researchers in this group investigate the entire geologic record. The understanding of geochemical processes in the earth and environmental sciences is obtained through the use of state-of-the-art analytical equipment for measuring elements and isotopic abundances from a wide range of materials.
