My research interests lie in spatial analysis, in both theoretical and spatially-grounded applications. Teaching focuses on GIScience (Geographical Information Science), GIS Systems, and Remote Sensing, and includes advanced issues in GIS, and research using GIS (crime analysis, health geography and landscape ecology).

Spatial analysis is an area of study that lies at the core of geography yet is inherently interdisciplinary and has relevance in the physical, health and social sciences. The thread that unifies my research is the understanding and insight that advanced spatial analysis brings to theoretical and applied research problems--often unveiling subleties that would otherwise have been overlooked.
I have three main areas of research interest:
- Theoretical investigations in spatial concepts. That is, exploring the theoretical underpinnings of spatial analysis, including issues related to scale, error and accuracy, visualization, fractals and data mining.
- The application of spatial analytical theory in subject areas where space and place are considered important explanatory elements. This includes a particular focus on biogeography (including health geography/medical biogeography and conservation biology) and, in particular, the distributions and occurrences of species (e.g. landform correlations). It also includes a focus on aspects of human geography, such as immigration, VGI, and land use applications.
- The social impacts of spatial technologies. That is, exploration of the social aspects of GIScience and geospatial technologies--the reflexivities between technology and society (e.g.public participation and the geoweb).

Special Projects: The Biodiversity of British Columbia
Three special initiatives are currently underway. Through the Biodiversity of British Columbia website and the biogeographic atlases of British Columbia, E-Flora BC and E-Fauna BC, we provide insights into our provincial biodiversity, what influences it, and how it is studied. The atlases contain a significant VGI or citizen science component .
