Postdoc position (microbiology, antibiotic resistance, microfluidics)

Posted by: Laboratory of Microfluidics and Complex Fluids, Institute of Physical Chemistry, Polish Academy of Sciences

Posted date: Oct-12-2019

Location: Warsaw, Poland

Job summary:

The Laboratory of Microfluidics and Complex Fluids at the Institute of Physical Chemistry PAS, Warsaw (group leader: prof. Piotr Garstecki) is offering a postdoctoral position within the project Microfluidic methods for quantitative antibiotic susceptibility assays with single cell resolution funded by the National Science Center MAESTRO 10 Project No. 2018/30/A/ST4/00036.

The objective of the project is to develop an analytical platform to encapsulate bacterial cells into droplets using microfluidics, incubate them and detect growth without optical labeling. In the envisioned protocol, the sample culture of cells will be serially diluted and each dilution split and mixed with multiple concentrations of antibiotic to screen inoculum density and antibiotic concentration with digital droplet assays. The assays at high and low inoculum density will allow us to count the fraction of populated droplets that produced dense colonies of bacteria. These counts will allow us to measure the single-cell Minimum Inhibitory Concentration (scMIC) level and the inoculum effect (IE) while the low-density screens will uncover the phenotypic heteroresistance, p(scMIC). The method will offer a wealth of information for research on the response of cells and bacterial colonies to antibiotics, and hopefully will guide more effective treatments regimens.

We are looking for a highly motivated postdoctoral candidate with strong background in biological sciences (microbiology, bioengineering, biochemistry, or similar) with focus on bacterium-antibiotic interactions and possibly with experience with droplet microfluidics.

The successful candidate will join a multinational and interdisciplinary team of scientist and will be responsible for i) developing droplet microfluidic systems for microbial testing of antibiotics in high-throughput and point-of-care (POC) formats and ii) investigating the microbiological factors associated with the development of phenotypic heteroresistance.


Design, construction and test droplet-based microfluidic systems for single-cell encapsulation and Antibiotic Susceptibility Testing (AST)
Microbial cell culturing
Monitoring the growth of a large number of single bacterial cells isolated in nanoliter droplets.
Determination of the heterogeneity of phenotypic response of individual cells in population
Data analysis, writing reports and scientific publications
Cooperation with researchers, including communication with English-speaking colleagues
Support and mentoring of PhD students


PhD degree in biological sciences (biotechnology, bioengineering, biochemistry) chemistry, physics or related fields
Experience with cell culture and antibiotic susceptibility testing is a must
Experience with standard bio-lab techniques (ELISA, Western blotting, qPRC, DNA isolation and sequencing, etc.)
Experience with confocal microscopy
Experience with microfluidic systems (design and fabrication) and their applications in microbiology is an advantage.
Experience in mentoring students is an advantage
