I am actively conducting research in the following areas:

• Geochronology and Geochemistry, Especially of the Holocene and Quaternary.
  • Geochronology of submarine and subaeial volcanism.
    • ²¹⁰Po-²¹⁰Pb dating. See also results from 9°50'N on the East Pacific Rise (EPR) the first application of this method to a submarine eruption in 1991.
    • ²¹⁰Pb-²²⁶Pb dating (page under construction)
    • ²²⁶Ra-²³⁰Th dating
    • ²³⁰Th-²³⁸U dating
  • Marine Corals and the Record of Past Hawaiian Sea Level.
• Mantle Geochemistry.
• Short-lived Radioactive Isotopes in Natural Materials.
• Mid-Ocean Ridge Dynamics and Volcanism.
• Marine Chemistry: Elemental Fluxes from Erupting Mid-Ocean Ridge Volcanoes.
• Environmental Chemistry of Uranium and Depleted Uranium in Hawaii.
