Department of Earth Sciences, South Parks Road, Oxford This work will provide a significant advance in our understanding of the transport of fluid and gas within crystalline rock environments over geological time. About you You will hold, or be close to completion of, a PhD in a relevant field (e.g. noble gas geochemistry, trace gas geochemistry, reactive transport modelling, ancient groundwater dating) together with experience relevant to the objectives of the projects. You will also possess sufficient specialist knowledge of gas geochemistry and have field and laboratory experience working with fluids and/or fluid inclusions. You must have the ability to manage your own academic research and associated activities and excellent communication skills including the ability to write for publication, present research proposals and results, and represent the research group at external meetings.
