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. My main interests are in plant remains and the ways these are used to answer (or raise) archaeological questions.
I visited the amazing Russian medieval city of Novgorod during five seasons of excavation between 1997 and 2002 (skipping one season because of lack of funding) and worked as a research assistant for Mick Monk from UCC. We looked at the waterlogged plant remains found in deposits from the city.
