Prof. Richard Evershed is the director of Bristol Biogeochemistry Research Centre and the Bristol node of the NERC Life Sciences Mass Spectrometry Facility and a member of the NERC Peer Review College. His research is inspired by a lifelong fascination with the natural world and the realisation that many opportunities exist to improve our knowledge of the key systems and processes that shape both modern and ancient environments by deriving molecular information from the various biological materials that lie at their focus. Evershed and his team are exploring new ways of deriving compositional information from organic remains of archaeological interest with the aim of improving our understanding of human activity in the past. The materials studied come from excavations in the UK, Europe, the Near East, Africa and the Americas, comprising a wide range of archaeological time periods, e.g. Neolithic, Roman, Bronze Age, Iron Age, Saxon, Medieval, etc. The findings accruing from this research are providing new information relating to otherwise intractable archaeological questions.
