postdoc NMR in Global Change Research

We offer a two-year postdoc position in NMR-based biogeochemistry. 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.
Project and Tasks:
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 related field and are excited by interdisciplinary work between biophysics, plant physiology and biogeosciences. Experience with NMR spectroscopy or stable isotopes is a merit. Applications should contain a CV, transcripts of your degrees, the names and contact information of two professional references, a list of scientific publications, and a one-page letter describing your motivation for this position.
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.
