I categorize myself as a quantitative geographer and computer scientist, with particular interests in geostatistical analysis and spatial data modelling. This combination of interests directed me into the fields of geographical and spatial analysis, geographical information systems/science, computer programming, and digital image processing and satellite remote sensing. My research activities and outputs have focused primarily on these main themes: the promotion, development, and evaluation of spatial interpolation techniques particularly for small-area population estimation; the methodological development and practical applications of the dasymetric mapping technique; the creation of population density surfaces for cross-areal estimation purposes; and the computation and application of spatial accessibility metrics particularly those derived from the two-step floating catchment area (2SFCA) methodology. The spatial interpolation problem (i.e. the estimation of data values across incongruent geographical units of analysis) is a problem that is intrinsic to a huge range of practical GIS applications. Solutions that I have played a part in developing through my research have had an impact across an eclectic mix of research fields including: environmental analysis (e.g. flood risk assessment); medical geography (healthcare provision and the designation of medically under-served populations); urban geography (neighbourhood identification, small-area population density mapping; spatial access to services); topics within the broad field of social science (e.g. crime analysis, environmental equity/injustice, deprivation estimation); and geographical information science itself (spatial accessibility, areal interpolation, spatial regression).
The impact of research is best judged by the value placed upon it by others. My research publications have received something close to 1000 citations to date, in peer-review articles published across a broad spectrum of academic journals. These include:
Applied Geography; Applied GIS; Annals of the Association of American Geographers; Australian Journal of Primary Health; Automation in Construction; BMC Health Services Research; The Canadian Geographer; Cartographica; Cartography and Geographic Information Science; Chinese Science Bulletin; Computers Ecological Modelling; Computer Vision and Image Understanding; Energy Policy; Environment and Urban systems; Environment and Planning A; Epidemiology; Geography Compass; Geographical Analysis; GeoJournal; GeoCarto International; GIScience and Remote Sensing; Health and Place; International Journal of Geographical Information Science; Journal of Quantitative Criminology; International Journal of Health Geographics; International Journal of Population Geography; Journal of Geographical Systems; Journal of Health Care for the Poor and Underserved; Journal of Homeland Security and Emergency Planning; Journal of Exposure Science and Environmental Epidemiology; Land Use Policy; Journal of Maps; Natural Hazards and Earth System Sciences; New Zealand Geographer; Photogrammetric Engineering and Remote Sensing; Population and Environment; Population Research and Policy Review; Population, Space and Place; The Professional Geographer; Quaternary Science Reviews; International Journal of Remote Sensing; Journal of the Royal Statistical Society: Series A; Renewable Energy; Social Science Research; Social Science and Medicine; Spatial Science; Science in China – Series E: Technological Sciences; Science of the Total Environment; Urban Geography; Vetinary Research; The International Journal of Applied Earth Observation and Geoinformation; International Journal of Geographical Information Science, Transactions in GIS.
My primary research interests at present are: Geographical accessibility and mobility modelling; The development of software tools to facilitate computation of E2SFCA accessibility metrics; The development and application of dasymetric mapping techniques; Population distribution modelling.
