For this position, we are interested in investigating the influence of microbial activity on carbonate biomineralization

Job description

Specifically, the main goals are to determine the mineralogical, chemical and microbial composition of carbonate minerals that have been formed under a wide range of physicochemical conditions (pH, T, salinity, etc). This work is important for interpreting carbonates in natural systems and their use in paleo-environmental reconstructions and the search for life in other planets.

Your duties
  • Participation and implementation of research projects with a focus on microbial-mineral interactions, analysis of environmental and experimental carbonate samples.
  • Supervision of students and participation in the management and administration of the geobiology laboratory, teaching and research.
  • Performance of laboratory culture experiments.
  • Process and interpret experimental data.
  • Present and promote the results obtained (reports, publications, conferences);
  • Collaborate with team, exchange and share knowledge.
  • Ensure compliance with milestones and deliverables.
