PhD position in Soil Science – How plant-microorganism-soil interactions in the Rhizosphere determine trace gas fluxes and the fate of root derived carbon in soils
A 3-year PhD fellowship is available in the Department of Geosciences & Natural Resource Management University of Copenhagen, Denmark, with an expected start 1 April 2023 or as soon as possible thereafter. The PhD is fully funded by the Novo Nordisk Foundation.
Soils not only provide the basis for human life, soils are also important to meet climate mitigation and biodiversity goals at regional, and even global scales. To reach these goals soil organic carbon plays a central role. For the storage and stability of soil carbon, plants and their roots are an important regulating factor. This regulation is based on the complex interplay of plant roots, soil microorganisms and mineral soil particles. Although we know of the importance of roots, we still do not fully understand how plant root traits affect the stability of soil carbon and the release of greenhouse gases. We also still lack a deeper understanding of the underlying biogeochemical processes between plant roots, microorganisms and soil particles that foster the persistence of originally plant root derived soil organic matter. The 5-year project “Understanding the regulation of soil carbon sequestration and greenhouse gas emissions by plant-root-microorganism interactions” is funded by the Novo Nordisk Foundation in the frame of the Ascending Investigator program, led by PI Assoc. Prof. Carsten W. Mueller. ‘RootCarb’ will provide both, the fundamental scientific understanding of how plant roots regulate soil carbon storage and greenhouse gas emissions, and practical proxies to be used in future agricultural management to sustain healthy and productive soils.
About your part in the project
In your project part you will target the fate of plant root derived organic matter as a function of plant-microorganism-soil interactions. Thus, together we will aim at better understanding the interactions of plant roots and their traits, microbial activity and the physical soil structure that regulate the fate of persistent soil organic matter. The work will range from highly controlled experiments at lab scale to field trials in which we will study root-microorganism-soil interactions in more detail. You will apply stable isotope tracing, classical soil biogeochemical methods as well as state-of-the-art spectromicroscopic imaging techniques to underpin quantitative data with in-situ process scale observations. You will put a special emphasize on developing experimental approaches that allow to directly study the interaction of plant roots, microorganisms and soil minerals at the microscale. Your major work will focus on tracing plant derived organic matter from the plant via root and microorganisms into different soil organic matter pools and its fate (trace gas measurements) in combination with the assessment of microbial community structure and activity.
The position is available for a 3-year period and your key responsibilities as a PhD student at University of Copenhagen are:
- Manage and carry out your research project according to the above research tasks
- Write scientific articles and your PhD thesis
- Disseminate your research at the institute, on international scientific conferences and to the broader general public
- Attend PhD courses (30 ECTS)
- Conduct secondment at a foreign research institution
- Work for the department (primarily teaching activities)
As a PhD student you will be part of the “Soil Science” research group led by Associate Professor, Carsten W. Mueller, Geography Section, University of Copenhagen, firstname.lastname@example.org, +45 35334125.
Requirements for applying for the position
To be eligible for the PhD program, you must have completed a degree program, equivalent to a Danish master’s degree (180 ECTS/3 FTE BSc + 120 ECTS/2 FTE MSc) related to the subject area of the project, e.g. soil science, geo-ecology, biology, biogeochemistry, forest science, agronomy or a closely related field. For information of eligibility of completed programs, see General assessments for specific countries and Assessment database.
We are seeking a highly motivated and ambitious individual with good interpersonal and communication skills. We are looking for and will prioritize applicants with combined experiences of:
- Good knowledge on soil biogeochemical processes with special emphasize on rhizosphere processes and soil organic matter cycling
- Practical experience in planning and conducting lab and/or field experiments including the study of plant-soil systems
- Experience with trace gas measurements and chemical soil analyses including soil organic matter studies
- Experience with soil microbiological techniques and imaging approaches are a merit
- Applicants must be fluent in both written and spoken English to a level sufficiently high for communication and dissemination at an academic level.
