Open PhD position

Open PhD position in Geochemistry at Institute of Earth Sciences, University of Lausanne

 

We have an opening for a PhD student in the domain of chemical and physical processes affecting the composition recorded in melt inclusions in MORB and OIB. This work implies a large amount of secondary ion mass spectrometer (SIMS), and other in-situ techniques like FEG-EMPA, and LA-ICP-MS. The candidate is expected to develop and apply analytical protocols, and to interpret the data using spatial modelling.

This study is of particular importance as melt inclusions compositions are used to infer melting processes, conditions of melt extraction, degassing and mantle source chemical characterization. All post-entrapment processes have then to be considered to interpret the data.

Requirements

We seek a highly motivated candidate with keen interest in volcanic processes, and small scale processes. Analytical skills or a keen interest to learn them is required, as well as an interest to develop quantitative models. Experience with melt inclusions and/or SIMS is beneficial. Good English skills and ability to work independently are essential. A Master’s degree or equivalent in Earth Sciences at the time of the appointment is required.

Further particulars

The initial appointment will be for a period of 1 year. After satisfactory evaluation of the initial appointment can be extended to a maximum duration of 4 years. The position starts during fall 2018 and will be paid according to Swiss standards for PhD fellowships. University of Lausanne is committed to promoting gender equality.

 

Applications should include a letter of motivation, summary of MSc thesis work, CV and the names of three referees. All these documents, combined in one PDF file, should be sent to Anne-Sophie Bouvier (anne-sophie.bouvier@nullunil.ch). Review of applications will start May 15th. The position will remain open until filled.

Call for proposals – deadline: November 1rst. 2017

Call for proposal is now open.

We strongly encourage submission of projects for which we already have developed the method and have the required standards. Projects needing development (method and/or standard) will be considered, but may be scheduled with a lower priority.

The proposal can be found here. Methods, reference material available and expected precision are described on those 2 pages: standards and analyses.

Please send the proposal, to:

Dr. Anne-Sophie Bouvier, Laboratory Manager of the SwissSIMS by e-mail (swisssims@nullunil.ch) no later than November 1st, 2017.
