The Institute of Geosciences, Faculty of Geography and Geosciences at the Ruhr-University Bochum, Germany invites applications for a full time (100%) position for duration of six years. The starting date is at the earliest possible time.
Researcher and Lecturer in Geochemistry
We are a team of stable isotope geochemists and sedimentologists aiming to reconstruct the paleo-hydrosphere, paleo-atmospheres and paleo-biosphere throughout Earth's history. Respective archives include (bio)chemical sediments (e.g., carbonates, silicates, sulfates, phosphates). We study the geological record, modern analogues and experimental samples using state-of-the-art analytical tools with a focus on triple oxygen isotope systematics.
As a research assistant, you will actively initiate and lead research projects within this broad spectrum. By following your main interests, you are expected to build an internationally renowned profile. Your duties include 4h/week in the semester which can include supervision of students and/or excursions. The successful candidate will be responsible for managing a part of the lab infrastructure.
Prerequisites are a PhD in Earth sciences or a related field. Preferably with a research focus on stable isotope geochemistry. Hands on experience with mass spectrometers and data reduction. Demonstrated experience in scientific writing and communication in English.
The successful candidate will have full access to the state-of-the-art analytical infrastructure. The laboratory of the working group includes:
* An ICP-OES for trace element analyses
* Three IRMS for conventional C, O and H isotopes on water, carbonates and methane as well as clumped isotopes.
* A TIMS for 87 Sr/86 Sr, plus respective clean lab facilities.
* A Neptune MC-IPMS, mainly used for Ca and Mg isotopes, plus clean lab facilities.
* An L2140-i Isotopic Water Analyzer (Picarro) for triple oxygen and hydrogen isotopes.
* A TILDAS CO2 spectrometer (Aerodyne Research) for triple oxygen isotope analyses.
* An IBEX carbonate sample preparation system used to generate CO 2 both for clumped isotope analyses (using a MAT352plus) and triple oxygen isotopes (using the TILDAS). The unique setup in Bochum enables simultaneous analyses on the same CO 2 gas from the same sample.
Furthermore, the institute comprises a central microanalytical laboratory which includes a microprobe, an SEM, a FIB-SEM and an optical KL microscope. A range of other instruments including XRF, XRD, NMR and a new LA-ICP-MS facility for in-situ trace element and isotope analyses are distributed in laboratories of other working groups. The Institute of Geosciences has moved to a new building several years ago, thus all laboratories and office facilities adhere to modern standards.
Financial resources to preform research, attend conferences and to publish results are available. Active support is given for proposal writing.
This infrastructure, in combination with the vibrant working environment provides a solid basis to develop and peruse own research ideas and to build or consolidate your research profile.
We look forward to receiving your application by 2026-01-22 via our online application portal .
