RESEARCH INTERESTS

Many of my earlier research activities were directed toward using a variety of paleomagnetic and rock magnetic techniques to gain a better understanding of the Earth's magnetic field and applying the knowledge obtained toward the solution of geologic problems.  More recently, a larger portion of my research activities has been directed toward the analysis and interpretation of gravity and magnetic surveys, using these potential-field data to model subsurface geologic/tectonic structures.
