Current interests fall broadly into three categories. These include:
- The use of geophysical data, predominantly magnetic and gravity data, to investigate the early history and development of small ocean basins (e.g. Gulf of Mexico and Red Sea), the tectonic evolution of oceanic plateaus (e.g., Caribbean Sea and the Ontong Java Plateau) and the structure of presently active (Mid Atlantic Ridge) and extinct (e.g. Coral Sea and Labrador Sea) mid-ocean spreading centers.
- Paleomagnetic investigations of local, regional and global tectonic problems including the structural/ tectonic history of orogenic belts (e.g., the Sierra Madre Oriental of northeastern Mexico, the Pontide Mountains of northern Turkey, and the Appalachian Mountains of the eastern US), magnetostratigraphic studies of both ancient and recent deposits (e.g., Ordovician carbonates in Newfoundland, and molasse deposits in Nepal), and rock magnetic property studies of shelf carbonates from the Permian Basin aimed at developing a better understanding of the role of migrating fluids on the acquisition of magnetic remanence.
- Geomagnetic time variations such as polarity reversals, secular changes, etc produced by internal processes within the Earth's core. The preparation and refinement of an internationally accepted geomagnetic field from magnetic survey and observatory data.
