I am a hydrogeologist who uses groundwater modeling techniques and field data to quantify the controls on groundwater flow and solute and heat transport through unconfined aquifers. I study this general problem in a variety of settings, from coastal barrier and barrier-island aquifers of the Outer Banks, southwestern England, and Wales to the alluvial aquifers adjacent to mountain streams in northwestern North Carolina. I use a variety of methods that combine hydrogeology with geophysics and groundwater modeling techniques to understand these systems.
