Other Teaching and Advising
I serve as the faculty advisor for the VT student branch of the American Society of Agricultural and Biological Engineers (ASABE). I also served as the Assistant Department Head for Undergraduate Studies for the BSE department during 2012-2018.
The overarching goal of my research program is to protect and restore stream and wetland systems, with three major objectives: 1) to determine the fundamental processes involved in streambank erosion and to develop improved measurement devices and mathematical models to predict erosion rates; 2) to develop more accurate computational models and software for the design of wetland systems; and, 3) to develop methods to minimize the impact of urbanization on stream ecosystems.
- “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.
- "Effectiveness of Low Impact Development in Protecting Channel Stability" - funded by the Chesapeake Bay Trust, the project goal is to use a watershed model (SWMM) and a reach-scale channel morphology model (CONCEPTS) to assess the effectiveness of environmental site design in reducing channel erosion downstream from urban development.
- "Evaluating streambank retreat prediction using the BANCS model in the Valley and Ridge physiographic province" - The goal of this project is to evaluate bank retreat predictions made using the BANCS model and to assess the sensitivity of the model to spatial and temporal variability in bank retreat measurements.
- "Do roots bind soil? Comparing the physical and biological role of roots in fluvial streambank erosion resistance." - The goal of this research is to quantify the relative contributions of the physical and biochemical aspects of soil reinforcement by plant roots.
- "Impact of bioretention on stormwater thermal load" - This study evaluates changes in stormwater runoff temperature and thermal load following treatment by bioretention cells.
"Improving the Success of Stream Restoration Practices" - The goal of this project is to improve our understanding of the conditions under which stream restoration practices “fail,” with the long term goal of improving the overall application, design, and review of stream restoration projects.
