Conducts applied research projects related to ecological flows, aquatic habitat quality, or endangered species critical habitat needs. My goal is to further USGS water-resources research incorporating my interests in ecology, hydrology, GIS, geomorphology, and ecosystem-management tool development. 

Ongoing Research Projects: 

  • Flow-Ecology Baseline Biological Richness Evaluation in Virginia: The current investigation will evaluate regional organizing variables for flow-ecology evaluations, evaluate extensive biological-richness data (fish and macro-invertebrates) in relation to drainage area and selected significant metrics from the phase-1 reseach, update and extend the previous modeling dataset to further test significant flow-ecology relations in Virginia.  
  • From the Mountains to the Sea: An innovative Water-Quality Network and Unique Collaborative Partnership: This successful partnership brings together Randolph-Macon College (RMC), Washington and Lee University (W&L), Virginia Commonwealth University (VCU), in partnership with the US Geological Survey (USGS) to foster growth in STEM through Summer student internship experience, awareness of USGS science in the class room, and increased the water-quality and streamflow monitoring network in the James River and tidal freshwater-estuary through new and enhanced technologies.
  • Endocrine Disrupting Contaminants (EDC) in the Shenandoah River and Fish Health - Sources and Biological Effects: Collaboration with the USGS National Research Program to evaluate point and non-point potential sources of EDCs and transport pathways in the Shenandoah River Watershed.  Partnership with Larry Barber, U.S. Geological Survey, Boulder, Colorado and Alan Vajda and David Bertolatus, University of Colorado Denver, Denver, Colorado.

Previous Studies: 

  • Water-Quality Effects on Rare and Endangered Freshwater Mussels in the Clinch River:  Multi-disciplinary USGS project incorporates water-quality, hydrology, geomorphology, biology, and land use change assessments toward an understanding of stressors causing decline in freshwater mussel populations. Outcomes should support forecasting ecosystem change in response to changes in land use, energy extraction practices, and climate.
