I have a long-standing interest in GIS, spatial analysis and landscape archaeology, with a particular emphasis on spatial modelling of stable isotope data, the role of web-GIS in collaborative research, and Neolithic occupation and stone working on the Yorkshire Wolds. Recent and ongoing research includes identification of the likely sources of the raw materials used in prehistoric wood carvings from Pitch Lake (Trinidad), determination of the possible geographic origins of the individuals cremated and buried in the Aubrey Holes at Stonehenge (UK), development of the web-mapping application for the Atlas of Hillforts of Britain and Ireland, creation of a map of biologically available strontium for Ireland, and geophysical and topographic survey on Lower Gypsades hill at Knossos (Crete). I am an active member of Computer Applications & Quantitative Methods in Archaeology (CAA) – I am currently an elected officer (Treasurer) on the CAA Executive Steering Committee and a co-opted member of the Scientific Committee as the Local Organiser for CAA2020 Oxford.

Archaeological Spatial Analysis: A Methodological Guide
This chapter introduces the spatial approaches which are used to determine the likely geographic origins of humans and animals and which in turn are used to understand mobility and migration. Two approaches are outlined – the first based on the calculation of residuals, and the second based on Bayesian statistics and maximum likelihood estimation. Both approaches compare the observed isotope measurement for an archaeological sample to the expected isotope measurement from baseline data for the area of interest. These approaches are applied to case studies from Annaghmare in Northern Ireland and Duggleby Howe on the Yorkshire Wolds. The case studies highlight the uncertainty implicit within the process of assigning an individual to a geographic region and the importance of using baseline data which adequately accounts for all of the factors that influence the spatial variation of the measured isotope tracer.

Hillforts: Britain, Ireland and the Nearer Continent
The Atlas of Hillforts of Britain and Ireland was a collaborative research project funded by the Arts and Humanities Research Council and carried out by the Universities of Oxford and Edinburgh, together with colleagues from University College Cork, Ireland. Building on a strong tradition of mapping dating back to the nineteenth century, the Atlas of Hillforts for the first time draws together evidence relating to all known hillforts – an iconic class of monument which forms the dominant component of settlement record in the first millennia BC and AD - on both sides of the Irish Sea. The digital version of the Atlas of Hillforts of Britain and Ireland was created using the ArcGIS platform, with the underlying data hosted on an ArcGIS Enterprise server and an accessible user interface created using Web AppBuilder for ArcGIS. It was launched at the end-of-project conference in June 2017 and has attracted over 275,000 visitors from 198 countries since then, with an average visit of over 6 minutes and more than 45 page views per visitor. The digital atlas has been used to promote National Parks, museums and public archives and has been highlighted as an invaluable research tool and educational resource for schools and universities.
Strontium isotope analysis on cremated human remains from Stonehenge support links with west Wales.

Cremated human remains from Stonehenge provide direct evidence on the life of those few select individuals buried at this iconic Neolithic monument. The practice of cremation has, however, precluded the application of strontium isotope analysis of tooth enamel as the standard chemical approach to study their origin. New developments in strontium isotopic analysis of cremated bone reveal that at least 10 of the 25 cremated individuals analysed did not spend their lives on the Wessex chalk on which the monument is found. Combined with the archaeological evidence, we suggest that their most plausible origin lies in west Wales, the source of the bluestones erected in the early stage of the monument's construction. These results emphasise the importance of inter-regional connections involving the movement of both materials and people in the construction and use of Stonehenge.
