  • Archaeobotany


I have worked as an archaeobotanist within the context of Irish commercial archaeology since the late 1990s, examining a wide range of material dating from the Mesolithic to the post-medieval period. I also had the good fortune to spend part of five summer excavation seasons (between 1997 and 2002) working as a research assistant with Mick Monk in Novgorod, Russia and looking at the waterlogged plant remains from this medieval city. My main interests are in charred plant remains and the ways these are used to answer (or raise) archaeological questions.
