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, 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.
