The working group on Quaternary Geology at the Institute of Geology and Mineralogy of the University of Cologne, Germany, invites applications for

Postdoc Position in Palaeomagnetic Dating and
Environmental Magnetism

within the framework of the Collaborative Research Center (CRC) 806 "Our Way to Europe - Culture-Environment Interaction and Human Mobility in the Late Quaternary" (see:

Objectives: The CRC project F6 ("Palaeomagnetic Dating, Stratigraphic Correlation and Environmental Magnetism of Sedimentary Records") primarily aims at conducting palaeomagnetic dating of sedimentary records investigated within the framework of the CRC 806, focusing on lake sediment cores but also involving loess sequences and cave deposits. Palaeomagnetic investigations shall focus on globally defined geomagnetic field excursions that have occurred over the last 120 ka, broad regional and global trends in directions and relative palaeointensity during the past 250 ka, and smaller-scale regional changes in palaeosecular variation (PSV) over the last 10 ka and potentially beyond. In addition, measurements of rock magnetic proxies, such as magnetic susceptibility, S-ratio and other grain size and compositional indicators, will be conducted on selected records to complement other proxies in reconstructing environmental and climatic histories. Palaeomagnetic measurements will be carried out using a cryogenic magne-tometer (2G Enterprises) at the University of Cologne that recently has been upgraded with: (a) a long core sample holder; (b) inline three-axis alternating field (AF) demagnetization coils; and (c) a direct current field coil system to impart an anhysteretic remanent magnetization (ARM) allowing determination of relative palaeointensity.

Position: The successful candidate will manage the palaeomagnetic and rock magnetic lab at the Universitiy of Cologne. Duties include (i) commissioning of the cryogenic magnetometer, (ii) advising of the group members of other CRC projects to take palaeomagnetic samples from sediment cores in the laboratory and sediment sections in the field and (iii) conducting palaeomagnetic and rock magnetic analyses in Cologne and potentially at collaborating laboratories. In addition, he/she will (iv) play a leading role in the interpretation of the data obtained, (v) jointly publish the data with members of the CRC projects that provide the sediment material, and (vi) ensure proper storage of the datasets obtained into the PANGAEA, GEOMAGIA50, and MagIC databases. The work will to some extent be supported by student assistants.

Qualifications: We are looking for highly motivated, team-oriented candidates with a profound background in palaeomagnetic and/or rock magnetic research. Candidates should hold a PhD in Natural Sciences, preferably in Geosciences or Physics, and have a solid publication record. Running and further developing the palaeomagnetic lab at the University of Cologne requires good analytical experience and management skills. Foreign candidates without prior knowledge should be willing to acquire German at a basic level.

Conditions: The successful candidate will be employed with a full-time postdoctoral position (ending June 30th, 2021) at the Institute of Geology and Mineralogy, University of Cologne, subject to the positive decision of the German Research Foundation (DFG). Further information about the working group can be found at Salary and benefits will be according to German Public Service Sector salary group TV-L 13.

Application: Please send your application (one pdf file), including motivation and interests, CV, and copies of certificates by email to Prof. Dr. Martin Melles (, who is happy to answer questions regarding the position, by June 1, 2017. The review of applications will begin immediately and continue until the position is filled. The University of Cologne is an equal opportunity employer in compliance with the German disability laws. Applications of women and disabled persons are particularly welcome.
