2016. “Childcare Provision Gap Analysis” commissioned by the Social Research and Information Division of the Welsh Assembly Government. The primary purpose of this contract was to undertake analyses of the spatial distribution of childcare provision relative to potential demand across Wales. The programme consisted of a series of advanced spatial statistical models using Two-Step Floating Catchment Areas Analysis, to evaluate the total capacity of childcare providers against the likely demand arising within local geographical levels (specifically Output Area and Lower Super Output Area). The research has had impact in terms of its use by the Welsh Government to explore geographical gaps in current childcare provision and to inform future policy development in regard to a manifesto pledge for free childcare provision for all working parents.
2015. “A customised GIS system for investigating inequalities in access to sporting facilities
in Wales”. Commissioned by SportWales. This project consisted of the development of a customised tool for use in ArcMap to provided bespoke accessibility analyses. The tool was bundled with a geodatabase containing pertinent open access data and 2011 census statistics which allowed the client to analyse variations in the spatial availability of sporting facilities across Wales and to investigate potential associations in provision with socio-economic characteristics of the local population demographics.
My primary research expertise is as a quantitative geographer and a computer scientist. My research interests are broadly based in the fields of spatial data modelling and geostatistical analyses, while my research activities and outputs have been focused in the fields of geographical and spatial analyses, geographical information systems/science, computer programming/software engineering, and digital image processing of satellite-derived remotely sensed data.
As is typical for academics, my research has followed a winding path. In my earliest days, under the guidance of Professor John Flenley, I became a pioneer in the field of “automated palynology”. Palynology is the study of the pollen grains produced by plants (and spores produced by fungi). The identification of pollen assemblages trapped in mud cores extracted from lake floors and bog lands is an important scientific technique. It allows the reconstruction of paleo-climates and paleo-environments. In simple terms, preserved fossil pollen help scientists to reconstruct and better understand past ecological and climatic conditions. Pollen analysis has considerable commercial value, often being used in the search for oil and gas reserves, and occasionally has been employed in forensic criminal investigations too. The analysis of pollen assemblages is traditionally a highly skilled task using visual identification of optical or scanning-electron microscopy imagery. This is time-consuming, costly, and requires the services of highly trained experts. In the early 1980’s machine vision, pattern recognition, and digital image processing were all niche areas of computer science. Professor John Flenley had the vision to question whether this embryonic technology could be applied to pollen identification – and this became the topic of my Ph.D. My Ph.D. thesis established the basic principle that potentially pollen identification could be automated by computing statistical image texture descriptors fed in to pattern recognition and classification algorithms. This pioneering work was far from a working solution, being limited to a small set of scanning electron microscopy imagery and half a dozen pollen taxa, but its publication in the Journal “Review of Palaeobotany and Palynology (“Computerized identification of pollen grains by texture analysis”, 1990, 64(1-4):197-203) has proven to be a catalyst for much on-going research and has now been cited in over 50 international peer-reviewed publications that continue to pursue the goal of a fully automated pollen recognition system. With enormous advances in computing power, digital image processing has since become an everyday activity, and automated palynology appears now to be a reality….

After my Ph.D. my research activities and outputs focused on the following themes: the development, evaluation and application of spatial interpolation techniques particularly those associated with small-area population estimation; methodological developments and practical applications of dasymetric mapping techniques; the creation of population density surfaces for cross-areal estimation purposes; and the computation and application of spatial accessibility metrics particularly those derived from two-step floating catchment area (2SFCA) methodologies.
Spatial interpolation (the estimation of data across incongruent geographical units) is a thorny problem intrinsic to a wide range of GIS applications. I have again made some pioneering contributions in this field. Most notably, with Professor David Unwin and our 1994 Cartographic Journal article titled “Generating and mapping population density surfaces within a geographical information system! (Carto.J. 31(1):21-26: DOI10.1179/caj.19188.8.131.52). This widely cited paper (300+ citations according to Google Scholar, 2018) was the first to re-ignite interest in the use of a hitherto largely unknown cartographic method named dasymetric mapping. We illustrated how it could be applied to the task of population estimation for small areas by using so-called intelligent areal interpolation techniques. Since 1994 there has been an explosion of interest and publication activity in the fields of dasymetric mapping and areal interpolation techniques.
Research impact is best judged by the value placed upon it by others. My research has impacted on an eclectic mix of research fields including environmental analysis, medical geography, urban geography, social science and geographical information science. This is evidenced by over 1250 citations to date in peer-review articles that have been published across a very 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.
