Isotope hydrology and biogeochemistry. Mixing models and hydrograph separation techniques. Sourcing and age dating of groundwater.

Research Interests

My research interests are focused on the processes controlling hydrologic fluxes in mountain regions and across greater earth systems.  Specifically, I work on understanding surface water and groundwater interactions in natural and human altered environments. I am interested in both the development of remediation strategies to improve water quality in disturbed settings and understanding how changing climate will impact water resource management practices across various spatial and temporal domains.
