I am currently responsible for oversight of drilling-related activities on the Hawaii Scientific Drilling Project that is completing a continuously-cored borehole into Mauna Kea volcano to a planned depth of at least 4.5 km. My scientific interests in the project revolve around hydrology of large volcanic/ocean islands and fluid transport and water-rock reactions occurring below the shallow basal freshwater lens. My other research interests include: study of radon release and transport in the vadose zone as an analog of volatile contaminant transport and as it relates to earthquake precursory phenomena; and the geochemistry of ocean island hydrothermal systems.
I also serve as the Director of the Center for the Study of Active Volcanoes at the University of Hawaii at Hilo. The program is a cooperative effort with the U.S. Geological Survey and provides training in the state-of-the-art of volcano hazards assessment and monitoring and conducts a variety of natural hazards outreach programs for the State of Hawaii.
