PhD student (f/m/x) in

biological physics & systems biology

Within the framework of Collaborative Research Center 1310

»Predictability in Evolution«, the Bollenbach group at the

Institute of Biological Physics investigates the evolution

of antibiotic resistance in microbial systems. The group

combines methods from molecular and microbiology with

concepts and techniques from physics.

YOUR TASKS

» Perform evolution experiments with E. coli lab strains

and clinical isolates that infect host immune cells,

particularly macrophages.

» Analyze evolving bacterial populations, in particular

using genome barcoding assays and next-generation

sequencing.

» Characterize the molecular mechanisms underlying

resistance and the role played by immune system

pressure.

» Develop theoretical models of resistance evolution in

collaboration with theorists.

YOUR PROFILE

» Very good MSc degree in evolutionary biology,

biotechnology, microbiology, biological physics,

or a related field.

» Strong interest in working in an interdisciplinary research

group between physics and biology.

» Previous knowledge of mammalian cell culture,

microbiology techniques, or programming is an

advantage but not essential.

» Strong communication skills are required.

» Applicants should be highly motivated and independent.

WE OFFER

» An interactive and supportive research environment

» A diverse working environment with equal opportunities

» Support in balancing work and family life

» Extensive advanced training opportunities

» Occupational health management offers

» Flexible working time models
