The over-arching theme of my research has been on the application of geophysics to environmental and engineering problems, where the target depth is typically the upper hundred meters. My most recent research has focused on how near surface geophysics can provide clues to groundwater/surface water interaction.

  • Using time-lapse electrical resistivity tomography to monitor flow in the hyporheic zone beneath beneath Crabby Creek, a stream near Valley Forge, PA, during the injection of a saline tracer.
  • Studying seepage at Mirror Lake, NH, using a resistivity, ground-penetrating radar, and seepage meters.
  • Seepage study at Lake Lacawac, PA, using resistivity, ground-penetrating radar, temperature loggers and seepage meters.
  • Using resistivity to look at patterns in seepage beneath Burd Run, a stream located near Shippensburg, PA, contrasted periods of high and low discharge in the stream.
