EXPERIENCE
Hydrologist, USGS North Carolina Water Science Center
08/2007 – Present
Since joining the USGS I have worked on projects that investigate how anthropogenic activities impact water quality and quantity in rivers and streams across the Southeastern US. Recent projects include a water quality and hydrodynamic model of the Roanoke River in support of protection and restoration of the riparian corridor. I have also worked on a regional-scale SPARROW model to analyze the transport of phosphorus across the landscape.
Agricultural Engineer, USDA-ARS Pasture Systems and Watershed Research Unit
03/2006 – 8/2007
While at USDA, I worked on best management practices related to field- and farm- scale phosphorus transport in manure amended soils.
Environmental Engineer, Tetra Tech Inc.
01/2001 – 03/2006
As an environmental consultant to US EPA and state agencies, I conducted water quality studies that led to approved Total Maximum Daily Loads. Responsibilities included technical oversight, application of watershed-scale water quality modeling and dissemination of results.

Status: Active SPARROW Modeling for North Carolina Watersheds
In North Carolina, excessive nutrient and sediment loadings have contributed to the degradation of surface-water quality across the state as a result of agricultural activities and population growth increases. To further understand the influences of human activities and natural processes on surface-water quality, the U.S. Geological Survey (USGS) developed the SPARROW (SPAtially Referenced...

A Regional Modeling Framework of Phosphorus Sources and Transport in Streams of the Southeastern United States
We applied the SPARROW model to estimate phosphorus transport from catchments to stream reaches and subsequent delivery to major receiving water bodies in the Southeastern United States (U.S.). We show that six source variables and five land-to-water transport variables are significant (p<0.05) in explaining 67% of the variability in long-term...

Mapping watershed potential to contribute phosphorus from geologic materials to receiving streams, southeastern United States
As part of the southeastern United States SPARROW (SPAtially Referenced Regressions On Watershed attributes) water-quality model implementation, the U.S. Geological Survey created a dataset to characterize the contribution of phosphorus to streams from weathering and erosion of surficial geologic materials. SPARROW provides estimates of total...

Simulation of Water Quality in the Tull Creek and West Neck Creek Watersheds, Currituck Sound Basin, North Carolina and Virginia
A study of the Currituck Sound was initiated in 2005 to evaluate the water chemistry of the Sound and assess the effectiveness of management strategies. As part of this study, the Soil and Water Assessment Tool (SWAT) model was used to simulate current sediment and nutrient loadings for two distinct watersheds in the Currituck Sound basin and to...

Assessing manure management strategies through small-plot research and whole-farm modeling
Plot-scale experimentation can provide valuable insight into the effects of manure management practices on phosphorus (P) runoff, but whole-farm evaluation is needed for complete assessment of potential trade offs. Artificially-applied rainfall experimentation on small field plots and event-based and long-term simulation modeling were used to...
