Robert Creaser specializes in radiogenic isotope geochemistry using the Re-Os, Rb-Sr, Sm-Nd, Pb-Pb isotope systems. A wide variety of geochemical phenomena and processes, mainly involving the geochemistry, origin and evolution of Earth's crust, are investigated using these isotope systems. Currently, research projects focus on the use of Re-Os isotopes for geochronology, such as: Re-Os geochronology and systematics of organic-rich sediments (black shales), application of Re-Os isotopes for direct dating of hydrothermal sulfide mineralization, Re-Os geochronology of fluid flow in sedimentary basins.
