• Paleotempestology
• Salt marsh paleoecology
• Sea level changes

Geochemistry

• Geochemistry of the Samoan hot-spot chain
• Hydrothermal alteration of oceanic peridotites
• Melt structure
• Seeking a hurricane signature in coral skeleton

Marine geology/geophysics/tectonics

• Oceanic Transform Earthquakes
• Large igneous provinces
• Long-lived normal faults in slow-spreading ridges
• Origin and evolution of rifted continental margins
• PLUME
• Seismicity, structure and fluid flow of the TAG hydrothermal system
• Submarine eruptions
• Subsurface imaging of hydrothermal vent fields
• Tectonics and magmatism of arc-continent collision
• Using high-resolution side scan sonar imagery of the seafloor

Paleoceanography

• Oceanic conditions in the past
• Persistence and pattern of rapid climate change
• Radiocarbon ventilation ages
• Reconstructing deep ocean circulation patterns
