The Faculty of Science at the University of Amsterdam invites applications for a Postdoctoral Researcher position in plant–microbe interactions, focusing on how bacterial communities colonize plant roots in a spatial and temporal context. This role sits within a highly interdisciplinary research environment combining microbiology, plant biology, and systems-level analytical approaches.
This postdoctoral position offers a rare opportunity to investigate dynamic plant–microbe interactions at high spatial resolution using cutting-edge microscopy and metabolomics. It is particularly suited for researchers interested in bridging plant biology, microbiology, and systems-level ecological analysis. Early application is strongly recommended due to strong international competition.
- Vacancy ID: 15019
- Deadline: May 31, 2026
- Salary: €3,546 – €5,538 (gross/month)
- Contract: 24 months (temporary position)
- Working Hours: 38 hours/week
- Start: As soon as possible
RESEARCH CONTEXT
Plant roots are colonized by highly diverse microbial communities that strongly influence plant health, growth, and stress resistance. However, how bacterial colonization is established in space and time on living roots remains poorly understood. This project addresses a key biological question: How do bacterial commensals compete, persist, and organize themselves along plant roots under natural community conditions?
The work focuses on:
- Host-specific microbiome assembly
- Bacterial competition and colonization strategies
- Root metabolite-driven microbial selection
Model systems include Arabidopsis thaliana and Lotus japonicus.
RESEARCH OBJECTIVES
The project aims to move beyond endpoint microbiome profiling and instead reconstruct dynamic colonization processes.
You will investigate:
- Spatial niche occupation along plant roots
- Influence of root-secreted metabolites on bacterial behavior
- Competitive displacement among bacterial strains
- Host preference mechanisms in microbial communities
METHODOLOGICAL APPROACH
This position combines experimental and analytical techniques, including:
- Fluorescence and confocal microscopy
- Molecular cloning and bacterial transformation
- Plant–microbe co-cultivation systems
- Metabolomics and spatial metabolite analysis
- DNA-based microbial tracking (16S-based systems)
You will also work with pre-existing host-specific bacterial culture collections, enabling controlled and reproducible experimental setups.
KEY RESPONSIBILITIES
- Design and execute controlled plant–microbe experiments
- Maintain rigorous experimental documentation
- Collaborate actively within the research group
- Contribute to scientific discussions and departmental meetings
- Lead scientific writing and publication of manuscripts
- Supervise Bachelor’s and Master’s students
- Contribute to research organization and shared lab responsibilities
