Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Research Interests 

I am interested in how subsurface geology controls the rate of groundwater movement and the dispersion of associated contaminates in glacial environments. In addition, I am interested in how unmanned aerial vehicles can be used to support various research objectives.
