Research Interests

Dr Petchey's research involves the application of radiocarbon techniques to the improvement of archaeological chronologies by the joint investigation of site taphonomy combined with sample specific radiocarbon (14C) effects in shell and bone caused by diet and environmental conditions. Her research is based on the premise that isotopic analysis (d13Ccollagen, d13Ccarbonate, d15N and d34S for bone, and d18O and d13C for shell), combined with geographic, archaeological and metabolic information, can help disentangle the mix of 14C from terrestrial and marine sources. This research has led the way in obtaining reliable calibrated radiocarbon data from Neolithic burials from Portugal and Lapita age sites in Fiji, Samoa, New Britain, Saipan and Vanuatu.
