Umeå universitet, Medicinska fakulteten

Umeå University is one of Sweden’s largest institutions of higher education with over 35,000 students and 4,200 faculty and staff. We are characterised by world-leading research in several scientific fields and a multitude of educations ranked highly in international comparison. Umeå University is also the site of the pioneering discovery of the CRISPR-Cas9 genetic scissors - a revolution in genetic engineering that has been awarded the Nobel Prize in Chemistry.

At Umeå University, everything is nearby. Our cohesive campus environment makes it easy to meet, collaborate and exchange knowledge, which promotes a dynamic and open culture where we rejoice in each other's successes.

The Faculty of Medicine, which consists of 13 departments, is responsible for biomedical research and courses in the field of nursing and health care and has an extensive research and graduate education in more than 80 subjects.

Within a project funded by the Swedish Research Council, the Department of medical biochemistry and biophysics offer a postdoctoral position in NMR-based biogeochemistry.

The position is for 2 years and the application is to be submitted in our e-recruitment system.

Project and work tasks:
Phosphorus used as fertilizer is a vanishing non-renewable resource, and the long-term response of plants to increasing atmospheric CO2 is a key knowledge gap in climate change. In an interdisciplinary environment with plant and soil scientists, your focus will be work on intramolecular distributions of heavy isotopes - isotopomers - for studying plant-climate interactions on centennial timescales. Furthermore, you will use 13C and 31P NMR to study C and P cycling in soils.

Isotopomer abundances reflect isotope fractionation of metabolic fluxes, and are therefore a unique tool to link enzyme regulation to global biogeochemistry (see Scientific Reports 2018, doi 10.1038/s41598-018-23422-2). We use experiments under controlled conditions to establish relations between isotopomer variation and metabolic regulation. The relations are used to interpret data from archives of plant material, to identify biogeochemical processes dominating on centennial time scales. You will focus on NMR sample preparation, measurements and data interpretation.

You hold a PhD in chemistry or a relevant field and are excited by interdisciplinary work between biophysics, plant physiology and biogeosciences. In normal case the doctorate exam should have been acquired within three years prior the last day for application to this position, unless special circumstances exist. Special circumstances include absence due to illness, parental leave or clinical practice or appointments of trust in trade union organizations.

Scientific environment:
The project is based at the KBC centre at Umeå University (, and is a collaboration between biophysics ( and the Swedish University of Agricultural Sciences (SLU). You will have access to state-of-the-art biogeochemistry sites and NMR spectrometers for advanced characterization of plant and soil organic matter and isotopomer analysis.
