Alexandra Bayliss is a British archaeologist and academic. She is Head of Scientific Dating at Historic England, and a part-time Professor of Archaeological Science at the University of Stirling in Scotland. Her research focuses on the construction of exact chronologies of European Neolithic archaeological sites, through the application of Bayesian statistical modelling of radiocarbon dates. Partnered with Alasdair Whittle from Cardiff University, Bayliss has conducted extensive research on causewayed and related enclosures in the United Kingdom and Ireland. The results of that study, a book co-authored by Bayliss, Whittle and Frances Healey, Cardiff University, titled Gathering Time: dating the early Neolithic Enclosures of Southern Britain and Ireland was named the British Archaeological Awards book of the year in 2012. From 2012 to 2017, Bayliss and Whittle led a project funded by the European Research Council (ERC). The project named "The Times of Their Lives" was a series of studies in precise chronologies and their implications, across several regions and phases of Neolithic Europe.Bayliss has conducted research on additional historic sites in the United Kingdom, Europe and Turkey, using the same methodology of statistical modelling of radiocarbon dates.
