Mark is a Research Geologist with Geology, Minerals, Energy, and Geophysics Science Center. He received a Ph.D. in Geology from the University of Wisconsin-Madison. Since joining the USGS in 1987, he has worked on interpretations of geophysical data for mineral and water resource issues, medical geology, and mineral resource assessments.
While his research, presently, is focused on extending mapped geology beneath cover and geophysical modeling of basins, Mark has expertise in geophysical interpretations of magnetic, gravity, and transient electromagnetic data in basins, identification of concealed lithology based on textural analysis of geophysical data, modeling the geologic/geophysical signatures of concealed mineral deposits, acquisition of ground-based magnetic, gravity, and transient electromagnetic data, modeling the soil habitat of Coccidioides sp. (etiological agent of valley fever), mineral resource assessments of public lands, and high performance computing.
