My primary research interests are in Paleomagnetic, Geomagnetism, Rock Magnetism, Scientific Ocean Drilling, Marine Geology and Geophysics, Plate Tectonics and Geodynamics, Paleoclimate and Paleoenvironmental Change, Chronostratigraphy, Exploration, and Data Analysis. Some of my active and past research projects include:
- IODP Expedition 339 (Mediterranean Outflow Water): Chronostratigraphic and magnetic studies of drill sites offshore Spain and Portugal.
- Antarctic geomagnetism, paleomagnetism, and environmental magnetism from drill cores (ODP, IODP, ANDRILL, and others).
- Paleosecular variation of the geomagnetic field over the past few thousand to several million years at sites around the world (Northern Atlantic Ocean, Blake-Bahama Outer Ridge, Cariaco Basin, Japan Trench, and elsewhere)
- The relationships between geomagnetic field variability, climate change, and orbital cycles.
- Stratigraphic analysis and petroleum potential of Melville Bay off NW Greenland in Baffin Bay.
- Paleointensity of the early Solar System from paleomagnetic and rock magnetic investigations of chondrules.
- Apparent polar wander, hotspot motions, and true polar wander.
- First Order Reversal Curves (FORCs), applied to characterizing magnetic interactions, coercivities, grain sizes, and compositions of synthetic and natural magnetic minerals.
- Rock magnetic properties of ocean basalts and the role of the upper oceanic crust in generating marine magnetic anomalies (from ODP Legs 200 and 206).
- Dating giant landslides off Oahu using cores from ODP Leg 200.
- Paleointensity determinations using a vibrating sample magnetometer (VSM).
