Research interests

I am interested in the application of non-destructive high resolution imaging and analysis techniques to rare and precious materials. By employing a range of in-situ, non-destructive or minimally destructive methods samples can be subject to rigorous analysis but also preserved for future study.
- Analysis of ancient materials
- Application of FIBSEM to precious meteoritical and geological materials
- Milling and extraction methods in the production of TEM wafers using FIBSEM
- 3D sample analysis
- In-situ analysis techniques
- Novel applications of high resolution microscopy
- Pallasites, iron meteorites and evidence of parent body processing
- Classification and study of newly discovered meteorites

Research Activity

Externally funded projects

The “iron” Bones of Seth; a study of the massive funerary fossil collection from Qau el-Kebir

RoleStart dateEnd dateFunding source
Lead01/May/201611/Sep/2017EES Egypt Exploration Society
Massive numbers of fossil bones were excavated from a burial shaft in Middle Egypt at the Qau el-Kebir cemetery, 1924. The excavators Flinders Petrie and Guy Brunton interpreted them as ritual offerings to the ancient Egyptian god Seth. As this area of Egypt was an ancient cult centre for Seth who was frequently depicted in artwork as a hippopotamus and the many hippopotamus fossils within the collection were obvious links. Considered important, many of the fossils were sent to the UK for further study, but a variety of practical issues obstructed their examination, with time records detailing their location were lost. This project will for the first time perform detailed scientifically analysis of the fossil collection to develop an understanding of its origins and potential ancient functions. This project is in partnership with the Natural History Museum, London and is funded by the Egypt Exploration Society.

Iron from the sky; a materials science and cultural study of ancient Egyptian iron

RoleStart dateEnd dateFunding source
Co-investigator01/Oct/201430/Sep/2015AHRC Arts & Humanities Research Council
An science and humanities investigation of Egyptian iron, its symbolism, practical application and influence. Incorporating surveys and analysis of iron artefacts and related materials from museum collections, early text references to iron. This study will involve a partnership with Cardiff University Archaeology Department.
