Rebecca’s expertise is in the characterisation of amorphous natural organic materials such as varnishes, adhesives and food residues. Her research applies chemical analysis to address questions concerning the source, production, use and alteration of these materials throughout the Museum’s collections. Her main interests are natural products such as resins, tars, gums and waxes.
Rebecca’s background is in archaeological sciences. She later specialised in analytical chemistry applied to ancient organic materials, in particular food residues. She further developed her skills in organic analysis in the commercial sector before joining the British Museum in 2001.
Rebecca maintains the Museum’s gas chromatography and mass spectrometry facilities.
