Research themes:
• magmatic processes and eruptions at active volcanoes on land and at sea
• coral reefs and sea level history.
• environmental geochemistry of heavy metals
Time periods of interest:
• primarily, active processes (occuring now or in the very recent past).
• secondarily, events that occured 1,000 to 500,000 years ago.
Locations:
• My group is conducting on-going research in Hawaii, Iceland, Tonga, and Mexico
Approaches and topics:
• tools: radiometric, geochemical, petrological and geochronological approaches.
• some examples:
