Biography

Ben is an Assistant professor in Archaeological Sciences. Ben’s role is divided between Archaeology, Forensics, Chemistry and the Analytical Centre.

Research

Bens research falls at the interface between analytical chemistry and archaeology. He is interested in the identification of the ‘archaeologically invisible’ by the correct application of analytical techniques. Some techniques are now fairly routine (such as Gas Chromatography - Mass Spectrometry (GC, GC-MS), Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) and stable light isotopic ratios (Isotope Ratio-MS)), although these techniques may have not been applied to novel materials. Some are new (e.g. High Performance Liquid Chromatography – Mass Spectrometry, HPLC-MS), but all require careful application due to problems of small sample size, contamination, complex mixtures, degradation and the reliability of the biomarker approach. Further details and some case studies. Archaeologically the aims are to find direct molecular, trace element and isotopic evidence for the identification and use of archaeological materials including ceramic vessels, traded goods and soils (in combination with conventional archaeological evidence). Related areas of interest include the analysis of modern natural products their degradation and preservation.
