Post-doctoral research position in marine paleoecology
Within the framework of the ERC Synergy project SEACHANGE, the Institute of Geosciences (Paleontology group) at the University of Mainz, Germany, invites applications for a 3 yr-postdoc position to reconstruct food web dynamics through compound-specific isotope analysis (CSIA) of mollusk shell organics etc. The University of Mainz has a vibrant campus with over 32,000 students and amongst others hosts the Institute of Geosciences, the Department of Chemistry and two Max Planck Institutes, which are equipped with state-of-the-art facilities.
The ERC Synergy project SEACHANGE, a joint research project of the universities of Exeter, York, Copenhagen and Mainz, aims to quantify the impact of major cultural transitions on marine ecosystem functioning and biodiversity. Target areas include NW Europe, eastern Australia and the west Antarctic Peninsula. The group at Mainz will identify temporal changes of the food web structure and determine the major primary producer groups at the base of the food web. For this purpose, the postdoc will focus on the δ15N and δ13C analysis of individual protein-amino acids via GC-C-IRMS and HPLC / GC-IRMS+EA. Proteins will be extracted from absolutely dated, live-collected and fossil shells, predominantly of long-lived species. Growth patterns (annual 'rings') in the shell will be used to temporally contextualize the protein samples (sclerochronology). Although CSIA is an established, though highly challenging method, the specific application to shell organics requires significant methodological refinement, which is one of the major task for the postdoc. The researcher will also help setting up the new laboratory devoted to CSIA.
The fixed-term appointment will be for a maximum of three years and ideally starts on 1 October 2020. Salary according to E13 TV-L (100% position) includes fringe benefits (health insurance etc.). The University of Mainz is an equal opportunity employer. Disabled persons with comparable qualifications receive preferential status.Interested individuals are invited to submit an application package including a motivation letter explaining why they apply and how they meet the hiring criteria outlined above, CV, copies of certificates (high school, BSc and MSc/diploma, PhD), degree transcripts (plus English or German translation) including an explanation of the scoring system, and addresses of at least two referees as a single pdf to Prof. Dr. Bernd R. Schöne, firstname.lastname@example.org, Institute of Geosciences, University of Mainz, Joh.-J.-Becher-Weg 21, 55128 Mainz, Germany. Application Deadline: 23 July 2020. Note, application review will begin immediately. The position will remain open and applications will be reviewed until the position is filled.
