Postdoctoral Research Assistant in Rhenium Isotope Geochemistry

Department of Earth Sciences
Grade 7: £34,304 - £40,927 per annum
Fixed term until 31/05/2024
Vacancy ID: 156153

The Department of Earth Sciences, University of Oxford, seeks to appoint a full-time Postdoctoral Research Assistant in Rhenium Isotope Geochemistry. The post holder will join a research team and report to the Principal Investigator Prof. Robert Hilton on the project "Rhenium isotopes to track carbon dioxide emissions by oxidative weathering" which is funded by a Natural Environment Research Council (NERC) standard grant. The project involves close collaboration with co-Investigators Dr. Alex Dickson (Royal Holloway University of London), Dr. Julie Prytulak (Durham University), and Dr. Mathieu Dellinger (CNRS, Chambéry, France).

The overall aim of the project is to develop and apply a new proxy to track oxidative weathering in Earth's past. The oxidative weathering of sedimentary rocks is a major source of carbon dioxide (CO2) to the atmosphere in the Earth System, but we currently lack a way to examine how it has varied in the past. Recent studies on the rhenium isotope system show that it offers the potential to do this. The post holder will undertake novel measurements of the rhenium isotope composition of sedimentary rocks. These measurements will be used to test theoretical predictions of Re mobility during episodes when continental weathering rates were very high and will pioneer the application of the proxy to the geological past.

The post holder will join a wider team, including a PhD student at University of Oxford and other researchers working on this theme. They will be responsible for managing their own academic research and administrative tasks, while also providing guidance to less experienced members of the research group. The post holder will be responsible for using specialist scientific equipment in a laboratory environment and will manage associated tasks.

The post holder will hold, or be close to completion of a relevant PhD/DPhil, together with relevant experience. They will possess sufficient knowledge in the discipline, and have demonstrable skills in the geochemical preparation of samples for elemental and isotopic analysis, including acid digestion and anion exchange column chemistry methods to extract and purify elements from rock or mineral samples. The post holder will also have experience of measuring novel isotope ratios by multi collector ICP-MS. They will have excellent communication skills, including the ability to write for publication and present research proposals and results.

For further details of the role please see the job description.

The deadline for applications is midday on 25 March 2022. You will be required to upload a CV and a Supporting Statement as part of your application. Please do not attach any manuscripts, papers, transcripts, mark sheets or certificates as these will not be considered as part of your application.

Applications are particularly welcome from women and black and ethnic minority candidates, who are under-represented in research posts in the Department.
