Samuel is a PhD candidate within the Organic Geochemistry Unit at the University of Bristol. His research seeks to address hypotheses surrounding diachronic and geographical changes in the molecular composition of parchment manuscripts and wax seals by GC/MS and HT-GC/MS; determine the isotopic composition of lipids within parchment and wax seals by GC-TC-IRMS and validate novel compound-specific approaches for radiocarbon dating.
