My research and teaching interests are in the general area of quantitative hydrogeology. I am most interested in problems that couple geologic information and observations with quantitative hydrologic models. One area of interest is the use of geologic information to improve our understanding of flow and transport process in heterogeneous sedimentary aquifers over a range of spatial scales. More recently, my research has focused on groundwater problems more prevalent in New England, including:
- Use of temperature to understand the spatial extent and dynamics of surface water-groundwater interactions in the hyporheic zone (Truslow et al., 2007);
- Quantitative and experimental analysis of the sustainability of ground source heat pumps in residential and commercial applications (Davis, 2007);
- Use of environmental isotopes to better understand groundwater flow paths and residence times in a mesoscale (Smith et al., 2007).
The ongoing research is part of a larger effort to build a more comprehensive and multidisciplinary understanding of hydrologic and biogeochemical processes in the Lamprey River Watershed.
I teach courses in Environmental Geology, Groundwater Hydrology, Contaminant Hydrology, and Groundwater Modeling. I am also developing a new freshman inquiry course in which students will learn about the hydrologic cycle through studies of a wide array of current water resource issues -- ranging in scale from local to global.
