Research Interests and Areas of Expertise
My research interests focus upon the development and application of spatial analysis techniques (i.e. GIS and remote sensing) to the study of the physical environment. Much of my work has focused on applications in the areas of hydrology, geomorphology, and environmental contamination. I am interested in digital terrain modelling and analysis and in the study of error in environmental modelling applications. I have several ongoing research projects that involve topographic data derived from laser altimetry (LiDAR). GIS software development and spatial analysis algorithm design have always been important components of much of my research.
Ongoing Projects
- Application of LiDAR DEMs to study gully erosion in the Peak District National Park, UK (with M. Evans, UofM)
- Using DEM-derived indices of wind exposure/sheltering to explain the spatial variability in nitrogen and other contaminants in moss species (with J. Rothwell, MMU)
- The spatial pattern and timing of ephemeral flows in headwater channels (with R. Bhamjee, UofG, C. Goulsbra and M. Evans, UofM)
- Automated techniques for the placement of sample outlets in drainage basin delineation (with J. Rothwell, MMU)
- Development of the Terrain Analysis System (TAS) GIS.
Professional Activities
- Peer reviewer for: Water Resources Research, Applied Geography, Computers & Geosciences, Photogrammetric Engineering and Remote Sensing, Hydrological Processes, International Journal of Geographical Information Science, and Earth Surface Processes and Landforms.
- Associate Editor (Science & Techniques) The Great Lakes Geographer, 2000, 2002.
- Symposium Organizer, International Perspectives on Spatial Modelling in Catchment Research, University of Manchester, UK, June 25, 2007.
