About this position
The University of Freiburg’s Chair of Ecosystem Physiology in the Faculty of Environment and Natural Resources is advertising a Doctoral Researcher (PhD) position in root ecology, ecophysiology, and root exudation.
The position is part of the DFG research unit FOR 5315 “FOREST FLOOR: Functioning, Dynamics, and Vulnerability in a Changing World”. The project investigates how soil drought affects compound-specific root exudation and root development patterns in three temperate tree species across the forest floor and mineral soil. The work is embedded in a broader interdisciplinary collaboration focused on forest floor functioning, ecosystem services, microbial communities, mycorrhiza, and drought responses.
Research tasks include regular sampling of compound-specific root exudates, minirhizotron-based root observations, upscaling of root exudation fluxes, drought experiments on European beech using rain-out shelters, sap flow and dendrometer measurements, and stable isotope work with 15N to study litter-derived nitrogen dispersal.
Applicants should hold a Master’s degree in Environmental Sciences, Geoecology, Biology, or a related field. A strong background in plant physiology, root ecology, nutrient cycling, and stable isotopes is expected. Experience with GC-MS, minirhizotrons, sap flow, and dendrometry is advantageous. The post also asks for excellent English, strong organizational skills, autonomy, flexibility, teamwork, and enthusiasm for field and lab work. A class B driver’s license is required.
The position is fixed-term for 3+1 years and paid according to TV-L E13 at 65%. The faculty notes the possibility to graduate in a formal PhD program. Applications are especially encouraged from women.
Apply in English via the University of Freiburg’s official job portal, citing reference number 00005179, and upload the required documents: application letter, CV, credentials, and a letter of recommendation. The deadline is 31 October 2026.
