Postdoc in NMR-based biogeochemistry

We look for a postdoc  to work on intramolecular distributions of heavy isotopes - isotopomers - for estimating biogeochemical fluxes on century timescales, a key unknown in Earth System Models. Quantification of deuterium and 13C isotopomers by dedicated NMR methods is a central part of the project (PNAS 2015, .

Project and Tasks: The goal of this project is to understand isotopomer signatures of biogeochemical fluxes from the leaf level to soil organic matter. The successful candidate will use experiments under controlled conditions to define isotopomer signatures. The results will be used to interpret data from century-old plant material, to identify biogeochemical processes dominating on long time scales. The work includes sample preparation,  NMR measurements and analysis in terms of isotope fractionation. The successful candidate will have possibilities for scientific development in a collaboration environment between soil sciences, tree physiology and biophysics.

Qualifications: We are looking for a person who is excited by interdisciplinary work at the interface between biophysics, physiology and biogeosciences. PhD in chemistry or related field. Applications should contain a CV including academic degrees, 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 Surroundings include the Swedish University of Agricultural Sciences (SLU, and the KBC centre at Umeå University (, Umeå, Northern Sweden. Working language in research and teaching is English. The successful candidates will use a state-of-the-art soil science lab and several long-term field manipulation experiments. KBC is equipped with state-of-the-art NMR spectrometers ( for advanced characterization of plant and soil organic matter and isotopomer analysis.
