Postdoctoral/Doctoral Research Fellow:
Terrestrial Hg biogeochemistry and surface-air fluxes

Project Summary:

This project attempts to assess elemental mercury outgassing from groundwater and subsurface soils and peat based on a novel, time-averaged passive sampling approach. Method development will require full calibration specific to these unique applications using co-located automated/pumped Hg0 measurements and a complete description of the method uncertainty assessed through field, laboratory, and modelling studies.


We are looking for a candidate with experience in Hg biogeochemistry. Additionally, experience in determining inter-matrix fluxes of contaminants (i.e., Hg), particularly between surfaces and the atmosphere would be highly desirable. Some German language skills beneficial, but not essential.


  • Multiple field sampling campaigns at contaminated and background sites across Germany and potentially in neighbouring countries and sample analysis.
  • Lab-based experiments to mechanistically assess the method.
  • Development of mechanistic models to assess the processes.


This position is available as a PhD. position or a postdoctoral research fellow (final decision will be based on the quality of candidates).

  • Eligible to work in Germany (including vaccination requirements)
  • Master's or PhD. in environmental science, geochemistry, chemistry or related field
  • Must have completed a master's or PhD level research thesis.
  • Excellent academic standing.

Additional skills and knowledge:

  • Experience with field sampling in environmental sciences.
  • Experience with experimental design.
  • Experience with analytical instrumentation, particularly with respect to Hg.
  • Experience with student supervision is a plus.
