My interest in geophysics is to better understand shallow karst processes such as sinkhole formation, soil/bedrock boundary delineation, and conduit and cave detection. For my masters thesis research at Missouri State I applied several near-surface geophysical methods to better understand the formation of a sinkhole within a retention basin, along with water flow through widened bedding planes near a spring. This included methods such as ground penetrating radar, electrical resistivity and induced polarization tomography, and very-low frequency electromagnetics.
For my recent karst spring thermal monitoring and modeling and research at Temple University I have used handheld FLIR cameras during fieldwork. One use of the cameras was to identify springs flowing into a stream to install temperature loggers.
