Field of Specialization: Near-Surface Geophysics

My research in near surface geophysics focuses on using the geophysical method, nuclear magnetic resonance (NMR), to understand processes occurring in the top 100 m’s of Earth’s surface. NMR measurements directly detect hydrogen protons water and are sensitive to their physical with chemical environment. Using NMR it is possible to non-invasively image the subsurface and obtain information about water content and pore properties. These measurements can be made from the surface or with an instrument lowered into a borehole and are typically used to characterize ground water aquifers. Through laboratory and field experiments, as well as computer modeling, we are developing new methods for interpreting NMR data to understand the link between NMR measurements and subsurface properties and processes. 

I am actively involved in science education research to engage students from groups historically underrepresented in the geosciences.
