Other Teaching and Advising
I 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.
- "Cost-Effective Methods for Reducing Sediment Loads in Lick Run" The goal of this study is to evaluate the use of stormwater management practices and/or stream restoration to reduce sediment loads to Lick Run, Roanoke, VA.
- "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.
- "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.
