GEOL 442: Field Geophysics


I am primarily interested in geophysical inverse theory and its applications, particularly involving the use of multiple types of geophysical methods to obtain better constraints on the geology of the subsurface. I have a particular affinity for electromagnetic methods, incorporating a priori information into the inversion process to obtain better results.

My previous work has been in the Cascadia subduction system, where I used passive seismic and magnetotelluric data both independently and combined to better understand the relationship between the subducting Juan de Fuca slab and the magma chamber beneath Mount Rainier.

My current plans include bringing these and similar tools to bear on some geological questions of a more local nature, including investigation of Eocene volcanics in northwestern Virginia, and near-surface characterization of Karst topography.
