I am a hydrologist in the New Hampshire office of the New England Water Science Center.  My overarching interest is in applied research that connects environmental geochemistry with human and ecosystem health.  Specifically I am interested in the occurrence, fate and transport of naturally occurring and anthropogenically produced contaminants in the hydrologic cycle.


My current work with the USGS is focused on using statistical models as a tool for understanding and predicting the occurrence of arsenic in groundwater.  Projects include investigating how changes in groundwater recharge may impact arsenic occurrence in domestic drinking water and comparing predictions of arsenic occurrence in groundwater to health impacts data.  I am also involved with a project characterizing iron fouling from roadways in order to develop predictive tools.  

My previous research was field and laboratory based and included examining the potential human health effects from exposure to biodiesel and petroleum diesel emissions, the occurrence of mercury in rainwater, and the occurrence of pesticides and herbicides in groundwater.  I have also worked with K-12 science educators and taught college level courses in geology and environmental science.
