Curriculum Vitae

The study of shallow earth systems relies on a broad group of sub-disciplines spanning a  range of earth sciences and engineering.  Objectives of geophysical characterization of shallow earth systems vary by application. The common goal is measuring the spatial distribution of solids and/or fluids in the subsurface.  My primary research interest is centered around quantitative analysis of wave propagation based geophysical data, particularly seismic reflection and ground-penetrating radar (GPR).  This includes developing an understanding of what physical properties it is possible to quantify, developing data analysis tools to make those measurements, and integrating physical property estimates in the solution of more general earth science problems.  I work on applying these quantitative methodologies to a broad range of problems including detecting contaminants in shallow groundwater systems, glacier hydrology, snow characterization, sea ice imaging, permafrost dynamics, surface water hydrology, basin stratigraphy, and shallow hydrothermal systems.  My research combines a rigorous computational approach with a comprehensive field study program.  Combining this basic framework with the interdisciplinary nature of my work provides graduate students with a variety of opportunities.  Additionally, I encourage and involve undergraduate students in many of my research projects.
