We are one of the largest and oldest universities in Europe and one of the most important employers in our region.
Our broad range of subjects, the dynamic development of our main research areas and our central location in Cologne
make us attractive for students and researchers from around the world. We offer a wide range of career opportunities in
science, technology, and administration.
The Saur Lab is part of the SFB1403, CEPLAS, and FOR5682, pro-
viding access to state-of-the-art research facilities and a vibrant,
interdisciplinary research environment. Our group investigates the
molecular mechanisms underlying plant–microbe interactions.
The successful candidate will perform molecular and biochemical
experiments to characterize the molecular functions of cell surface-
localized receptor homologs in regulating interaction with pathoge-
nic fungi and other microbes (TV-L 13, 65%).
YOUR TASKS
The primary goal of this research is to investigate the function of cell
surface-localized receptor homologs in regulating microbial invasion
of dicots (A. thaliana, N. benthamiana) and monocots (barley).
This research will involve the use of available genetic material
and the generation of mutant and chimeric constructs of the cell
surface-localized receptor SRF3 to mechanistically assess its esta-
blished role in
» microbe-triggered immunity
» cell death-related immune responses
» iron-related processes
(doi: 10.64898/2026.01.08.698370) using transcriptomic (RNAseq),
phenotypic (plant immunity measurements & microbial proliferation
assays) and biochemical assays (protein-protein interaction assays).
YOUR PROFILE
» An MSc (or equivalent degree) in Biology or a related field, with
expertise in molecular plant–microbe interactions and/or plant
immunity
» A strong interest in the molecular mechanisms of plant–mi-
crobe interactions (incl. pathogens and/or natural microbiota
members)
» Experience in molecular cloning, protein–protein interaction
and/or RNAseq analyses will be considered an advantage.
» Excellent English communication skills, both written and spoken
WE OFFER
» A scientifically stimulating environment with a low hierarchy
» A diverse working environment with equal opportunities
» Support in balancing work and family life
» Flexible working time models
» Extensive advanced training opportunities
» Occupational health management offers
