Postdoctoral Fellowship in Soil Contaminant Biogeochemistry

We are looking for a creative, qualified and motivated postdoctorate-level young scientist, in the context of the ongoing ANR-funded collaborative research project DECiSIvE at LHyGeS research unit, University of Strasbourg (partner of the project).

The project involves (i) the acquisition of biomolecular (functional genes/degrading microorganisms) and stable isotope data (compound-specific isotope analysis) from pesticide degrading cultures; (ii) the acquisition of biomolecular and stable isotope data from lab-scale soil column experiments with pesticides; (iii) the mechanistic interpretation of pesticide dissipation in soil. The successful candidate will help develop conceptual approaches and new integrative experimental tools to monitor and understand transformation of pesticides in soil. Work to be performed by the postdoctoral fellow at University of Strasbourg will include:

  • Experimental work on pesticide degrading microorganisms and soil profiles, sampling approaches and chemical analyses to study pesticide dissipation in soil
  • Application of biomolecular tools to evaluate microbial diversity associated to pesticide degradation
  • Application of methods for stable isotope analysis of pesticides in soil
  • Working collaboratively within a multidisciplinary team and with external partners
  • Preparing peer-reviewed scientific publications and presentations for scientific conferences.

Applications will require:

  • A PhD degree in environmental microbiology, and/or environmental chemistry within the last five years
  • A corresponding publication record in peer-reviewed journals
  • Experience in microbiology/microbial ecology and analytical chemistry
  • Good command of the English language (written and oral)
  • Communication skills and an ability to work in an interdisciplinary team with scientists, engineers, and technicians
  • A working knowledge pollutant transformation in soil, stable isotope analysis, and/or CSIA, stable isotope probing of microbial degradation of pollutants, as well as an international research experience, will be additional assets.

The position is for two years. We offer salary and social benefits according to French public sector regulations. Please submit your application, including letter of motivation, CV, list of publications, copies of certificates, and the names and contact information of potential referees, and all other requested information to (CNRS portal). Scientific contact: Gwenaël Imfeld (

Closing date for applications is April 30, 2019. Preferred starting period will be between September 2019 and December 2019.

Additional information:

The Laboratory of Hydrology and Geochemistry (LHyGeS, UMR 7517 CNRS; focuses on flow and transport in continental hydrological systems. Research activities associate experimental and isotopic biogeochemistry with hydrology to understand processes at different scales and to develop transport models. LHyGeS conducts lab- and field-scale experiments to study transport of water and contaminants, and the team focuses on the transformation of pollutants using compound-specific isotope analysis (CSIA) in catchments, soils, and aquifers. Research at University of Strasbourg covers all areas of science, and encourages interdisciplinary and international collaborations. Located at the heart of Europe in a trinational region (France, Germany, Switzerland) of dynamic economic activity, Strasbourg is a pioneer city in terms of environmental awareness in France, and a very pleasant place to live in.
