Research and Academic Interests:
Applications of paleomagnetism to geologic problems, particularly in orogenic belts (e.g., Western Cordillera of North America, eastern Himalaya syntaxis); geomagnetic field behavior; relations between rock magnetic properties and igneous and sedimentary processes; the great "battle": science vs. creationism.
