To trace the sources, sinks and transport mechanisms of elements among the major Earth reservoirs via magmas, fluids and gases, in deep- and shallow-level systems.
Rates and mechanisms of Earth processes
To develop and apply isotopic dating techniques for determining the rates and understanding the mechanisms of geological processes ranging from global tectonics to surface weathering and ore formation.
Mineral and gas hydrate resources
To characterize and understand the origin of metallic ore deposits and gas hydrate resources, exploitation strategies, from case studies, experiments and modeling.
