Other Teaching and Advising
I serve as the Assistant Department Head for Undergraduate Studies for the BSE department. I also am collaborating on a curriculum development project with partner institutions in the US (University of Illinois) and Europe (University College Dublin, Universidad Politecnica de Madrid, University of Bari (Italy), and Agricultural University of Athens). The project is funded through the Atlantis program of the U.S. Department of Education and the European Commission.
My research program focuses on the protection and restoration of stream and wetland systems. A major goal of my research program is to investigate the interactions between stream-side vegetation and stream channel stability, including quantifying how vegetation reinforces streambanks and changes flow energy during storm events. I am also interested in improving testing procedures and models of cohesive streambank erosion. I am also collaborating with Lee Daniels (CSES) and Richard Whittecar at Old Dominion University to develop an improved wetland design model. My role in the project has been to improve current surface water hydrology calculations used in common design models. Another objective of my research program is to minimize the impacts of urban development on streams. Using a grant from the VA Water Quality Improvement Fund, my research team designed, constructed, and monitored two innovative best management practices (BMPs; a bioretention area and a structural soil infiltration trench). Based on these results, we developed BMP design and maintenance recommendations to increase the adoption and success of such BMPs. The next step is to identify the physical, chemical, and microbial processes in forest soils that can be restored in urban environments. I am collaborating with Leigh-Anne Krometis (BSE), David Sample (BSE) and Brian Strahm (Forestry) to explore these processes. Lastly, to advance the understanding of linkages between management actions and ecosystem response, I am working with faculty across campus to develop and maintain the StREAM Lab, a large scale stream laboratory.
- “Wetland Water Budget Modeling” – this multidisciplinary project funded by the Piedmont Wetlands Research Program focuses on the development of a wetland water budget model to improve the success of mitigation wetlands.
- “Surface Water Flow Resistance to Emergent Wetland Vegetation” –funded by the Piedmont Wetlands Research Program, the goal of this project is to develop models to predict friction factors for emergent wetland vegetation.
- “Influence of Stream Temperature on Streambank Erosion” – this project is examining the effect of changes in stream temperature, due to climate or landuse change, on the erosion of cohesive streambank soils.
