PhD Position: Role of Root Mucilage in Water and Phosphorus Uptake in Semi-Arid Environments (RootMucilage Project) Forschungszentrum Jülich in Germany

This PhD position is part of the RootMucilage project, funded by the German Research Foundation (DFG), and hosted at Forschungszentrum Jülich in collaboration with the Technical University of Munich, University of Tübingen, and RPTU University Kaiserslautern-Landau. The project investigates the role of root mucilage in water and phosphorus uptake in semi-arid environments, focusing on emergent plant-scale behaviors and the formation of moist microbial rhizosphere habitats. By contrasting maize genotypes, the research aims to understand how mucilage and low molecular weight organic carbon compounds influence root water and phosphate uptake.

The successful candidate will build on the process-based soil-rhizosphere-plant model developed at the Agrosphere Institute, which integrates a 3D functional-structural approach (CPlantBox) to simulate plant growth, plant-soil interactions, and rhizosphere microbiome dynamics. Responsibilities include extending the model to simulate 3D root architecture development, mucilage and organic carbon release, and their fate and function in soil. The candidate will set up virtual representations of column and lysimeter facilities at ICRISAT, India, perform scenario simulations, participate in conferences, collaborate with national and international partners, and prepare scientific publications and project reports.

Applicants should have a Master’s degree in bioengineering, environmental sciences, soil science, or applied mathematics, with knowledge of plant and soil sciences, differential calculus, and programming skills. Strong communication and organizational abilities, proficiency in English (minimum B2 CEFR level), and willingness to travel to India are required. The position offers a vibrant international work environment, flexible working hours, 30 days of annual leave, access to exceptional research infrastructure, and opportunities for further scientific and technical training. The doctoral researcher will benefit from structured continuing education and networking via JuDocS, targeted services for international employees, and a diverse, inclusive campus environment.

The position is fixed-term for 3 years, with funding aligned to 65% of pay group 13 of the TVöD-Bund collective agreement, plus a special payment ('Christmas bonus').
