The project is a French-German collaboration funded by the French Agence Nationale de la Recherche (ANR) and the Deutsche Forschungsgemeinschaft (DFG; German Research Foundation). The French collaborators, Dr. Naoise Nunan and Dr. Xavier Raynaud, belong to the Institute for Ecology and Environmental Sciences in Paris (SU/CNRS). They are specialized on studying interactions of microbial processes with soil carbon fluxes and apply spatial modeling approaches. The German side is coordinated by Dr. Steffen Schweizer from the Chair of Soil Science (Technical University of Munich; TUM) investigating organo-mineral interactions governing the storage of organic matter in soils and characterizing these processes at the microscale using spectromicroscopy techniques. By bringing together complementary expertise on physicochemical carbon storage mechanisms and soil microbial carbon fluxes, we aim to jointly extend our understanding of the interplay between the spatial distribution of organic matter and its microbial decomposers across pores by focusing on the impact of organo-mineral interactions. These interactions are specifically relevant in times of changing climate that can disturb the storage of organic carbon in soils.

In this collaborative project, we will develop a novel artificial microcosm approach with defined porosity and soil mineral setups. The labeling of organic matter with the stable isotope 13C will allow tracing its impact on microbial carbon dynamics across different pore size classes. Our scheduled incubation experiments also contain climate-change related disturbances. The planned activities integrate tracing the fate and the transformation of organic matter into microbial biomass and CO2 and characterizing organo-mineral interactions. A correlative spectromicroscopic workflow, including NanoSIMS, will integrate cutting-edge imaging approaches.

The Chair of Soil Science at the Technical University of Munich invites applications for a 3-yr doctoral position focusing on the investigation of organo-mineral interactions and the method development. The starting date is planned on approximately 1st of March 2023, a later starting date could be discussed. Candidate profile: We are looking for a highly motivated, co-operative person with a strong background in soil science, or related biogeochemistry disciplines. The ideal candidate has demonstrated her/his ability to conduct research, from investigating a defined research topic to deriving an improved process understanding and communicating the results. Moreover, the ideal applicant should have some background in soil organic carbon analyses, or be keen to learn about and utilize these methods. A strong command of English is indispensable. For international candidates, knowledge of German would be beneficial. The effective exchange and collaboration within the French-German partnership will be crucial and also include some occasional travels. The salary is the German standard for doctoral students (TV-L E13 65%). The Technical University Munich is an equal opportunity employer and encourages women to apply. Disabled applicants with equal qualification and aptitude will be given preferential consideration.

Your application should include a letter of motivation, a CV, academic transcripts (non-official copies are acceptable) and contact details of two academic references. In your letter of motivation you may discuss your research ideas and interests, your personal approach in relation to the project description, and describe how past academic or non-academic experiences have prepared you for this position. Please send your application as a single PDF by email with the subject “PhD position SoilPACMAN” by 5th January 2023 to application.boku[at] Applications are reviewed on a rolling basis until the position is filled. For any detailed questions related to the project you can contact Dr. Steffen Schweizer Dr. Steffen Schweizer.
