Research

My primary research focuses on the integrated use & development of near surface geophysical methodologies to understand near-surface material geophysical properties and groundwater recharge/movement in mountain headwater environments, hydrothermal areas, the Earth’s Critical Zone, and contaminated (or threatened) municipal aquifers.

Due to a vast accumulated experience in applied, theoretical and manufacturing near-surface geophysics as well as exploration seismology, I work extensively and often with all current near-surface geophysical instrumentation (i.e. surface/borehole reflection and refraction seismology, surface/borehole/marine DC resistivity - induced polarization - self-potential, borehole geophysical logging, surface/borehole nuclear magnetic resonance, total & gradient Magnetics, multifrequency “shallow” electromagnetics, transient “deep” electromagnetics, controlled source and natural magnetotellurics, ground penetrating radar and gravimetry).  Also, I operate and collect soil and rock core samples with the WyCEHG 7822DT Geoprobe drill rig and manage the near-surface materials properties testing lab in the basement of the Geology building.

Currently, I have ongoing research hydrogeophysical projects in & around Laramie, WY; Yellowstone NP; Calhoun, SC, and Los Alamos, NM.

Finally, I am the facility manager of the Wyoming Center for Environmental Hydrology and Geophysics FINSE (Facility for Imaging the Near and Subsurface Environment) hydrogeophysics group.
