Transition from genetic to phenotypic antibiotic resistance in de novo bacterial mutants Funded through OPUS-22, 2021/43/B/NZ1/01436, 32/2023

Project leader

Dr Bartłomiej Wacław


The purpose of this project is to investigate the population dynamics of antibiotic-resistant mutants of the bacterium E.coli immediately after their emergence due to spontaneous mutations.

Job description

Number of vacancies


Key responsibilities include

We seek a talented post-doctoral researcher to contribute to the project “Transition from genetic to phenotypic antibiotic resistance in de novo bacterial mutants”.
The project will involve creating a microfluidic device suitable for live imaging of 109 bacterial cells, tracking antibiotic-resistant spontaneous mutants that evolve in the device, and measuring their growth rate over several generations. This will be complemented with DNA sequencing and in situ visualisation of mutations using a CRISPR/Cas9-based technique developed by another post-doc.

Other team members will use mathematical modelling to interpret the data and predict the effect of the genotypeto phenotype transition on the dynamics of bacterial infections.
This position is ideally suited for a person with experience in biological applications of microfluidics, optical imaging of living matter (cells, bacteria), or biological image analysis.

Main responsibilities:
1. Planning and execution of specific elements of the research program, acting under general guidance of the supervisor. This will involve deciding (with the supervisor) on the detailed direction of the research, formulating a
strategy for day-to-day research work, implementing the strategy (without close supervision), interpreting obtained data, drawing conclusions, and reporting progress to the supervisor.
2. Communicating research results to team members and collaborators at IPC and other institutions through talks and discussions, as well as learning about others’ research through seminars and journal clubs.
3. Assisting with supervision of junior researchers (Master and PhD students), where appropriate.
4. Writing reports and scientific papers.
5. Attending and presenting at workshops and conferences.
6. Keeping up-to-date with relevant scientific developments through literature review.

Additional information

About the Dioscuri Centre
The Centre’s main objective is to better understand bacterial growth and evolution in the natural environment of pathogenic bacteria: the interior of an animal cell and animal secretions. The members of the Centre use experimental in vitro models of infections, computer simulations and mathematical theory to create data driven, quantitative models of bacterial growth and evolution in these environments. Research performed in the Centre will contribute towards the understanding of bacterial infections and the evolution of antimicrobial resistance in animal and human hosts. The Centre collaborates with research institutions in Germany, the UK and the US. The Centre is co-funded by the Polish Ministry of Science and Higher Education and the German Federal Ministry of Education and Research, with additional support coming from NAWA.
