Fire ash is ideally suited to mineral magnetic studies. Both modern (generated by controlled burning experiments) and archaeological ash deposits have been studied, with the aim of identifying and quantifying fuel types used in prehistory. Low temperature magnetic measurements were carried out on the ash samples using an MPMS2 SQUID magnetometer. The low temperature
thermo-remanence cooling curves of the modern ash display differences between fuel sources. Wood and well-humified peat ash display an increase in remanence with cooling probably related to a high superparamagnetic component, consistent with room temperature frequency dependent susceptibilities of over 7%. In comparison fibrous-upper peat and peat turf display an unusual
decrease in remanence, possibly due to an isotropic point of grains larger than superparamagnetic in size. The differences have been successfully utilised in unmixing calculations to quantify fuel components within four archaeological deposits from the Northern and Western Isles of Scotland.

My research area focuses on the archaeology of the first millennia BC and AD across the Atlantic Seaways. I have co-directed excavations and landscape surveys in the Western Isles and Argyll, with colleagues in various universities and worked abroad in Syria, Romania and France on excavations. I am currently an Honorary Fellow of the University of Edinburgh where I have taught various courses in Archaeology.
After completing my PhD I worked at the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) as the Aerial Survey Liaison Officer in the National Monuments Record for Scotland (NMRS) from 2001 to 2005. During this period I was also Secretary of the Scottish Aerial Archaeology Group, and a member of the Aerial Archaeology Research Group (AARG).
From 2001 to 2004 I was elected to the Board of Archaeology Scotland (then the Council for Scottish Archaeology) as Honorary Secretary, and served as elected Vice President from 2004 to 2010. I am currently the elected Vice Chair of the Built Environment Forum Scotland (BEFS) and convener of their Historic Environment Working Group (HEWG) and Historic Environment Bill taskforce.
I am currently Director of the Society of Antiquaries of Scotland, the oldest antiquarian Society in Scotland, and second oldest in the UK, founded in 1780. Further information on the Society is available through the website www.socantscot.org. As Director I manage the Society with a small staff team, servicing over 3000 Fellows across the world.
SELECTED CURRENT PROJECTS:
'Uig Landscape Survey Project', Lewis, Western Isles (UK). Co-directed four seasons of landscape survey and excavation of four archaeological sites across the Uig Peninsula, Lewis from 1995 to 1998. Post-excavation nearing completion. Principal funding bodies: Historic Scotland (UK), University of Edinburgh (UK), Carnegie Trust for the Universities of Scotland (UK), Uig Estate and the Gearing family (UK).
'Glashan Dun', Argyll (UK). Co-directed a season of excavation and survey at this Iron Age roundhouse adjacent to the Glashan crannog. Post-excavation nearing completion. Principle funding bodies: Historic Scotland (UK), University of Nottingham (UK).
