Institute for Biological Physics | Bollenbach Group

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.

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
