My research interests are focused on the development and application of spatial analysis techniques (i.e. GIS, remote sensing, and digital terrain analysis) 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. GIS software development and spatial analysis algorithm design have been important components of much of my research.
Research Statement: The novel techniques and data provided by recent advances in the fields of geographic information systems (GIS), remote sensing, and digital terrain analysis (DTA) have resulted in significant improvements in our understanding of processes operating in catchments. My research interests focus on the development and application of spatial analysis techniques to the study of catchment processes, particularly related to hydrology, fluvial geomorphology, and environmental pollution. Although these new approaches to analysis and sources of data can provide significant insight, they are not without limitations. A major component of my work is concerned with assessing the role of error in spatial analysis. The goal of this work is to quantify the reliability of various data and models that are commonly used to inform policy.
