Goethe-University Frankfurt
Postdoctoral or PhD research position in clumped isotope geochemistry

The Institute of Geosciences at the Goethe University Frankfurt am Main, Germany, invites applications for a

Postdoc position (E13 TV-G-U) or
PhD position (E13 TV-G-U, 75%-part time)

in clumped isotope geochemistry. The position is funded by the German Research Foundation (DFG) for a peri-od of 27 months (Postdoc) or 36 months (PhD position). The salary grade is based on the job characteristics of the collective agreement (TV-G-U) applicable to Goethe University.

The candidate will be responsible for a project in which the thermophysiology of mosasaurs is reconstructed. As part of this project she/he will expand the in-house repertoire of analytical techniques for carbonate clumped isotopes to even smaller sample amounts, screen mosasaur teeth for diagenetic alteration and analyze their clumped isotopic compositions. Though the focus is on Δ47 in (bio)apatites, the candidate will have the oppor-tunity to perform dual clumped isotope ( Δ47, Δ48) analyses on selected (bio)apatites. Moreover, if interested, she/he is encouraged to contribute to ongoing research related to dual clumped isotope analysis of pure car-bonates. Dual clumped isotope analysis represents a new promising tool to identify if (and to what extent) kinet-ics and/or diagenetic processes affected the clumped isotopic composition of a given carbonate-bearing phase in addition to temperature.

The successful candidate should hold a PhD and/or MSc in geosciences, chemistry, physics, or a related field at the time of appointment. A strong motivation for research is prerequisite. Expertise (hands-on experience, data publication, data presentation) in the field of clumped isotope geochemistry is mandatory. Hands-on experience with the Kiel IV Device would be a benefit.

Appointment at postdoctoral level is preferred, however PhD candidates fulfilling the above criteria will also be considered. The position starts in August 2020 or soon thereafter. Applications should be sent electronically as a single pdf-file to Prof. Dr. Jens Fiebig (Jens.Fiebig@em.uni-frankfurt.de) until 15.04.2019. The pdf-file should contain a CV, names and email addresses of three referees as well as a letter describing motivation, research interests and recent research accomplishments.
