Project description

Rapid antibiotic susceptibility tests (rASTs) are highly desired in modern clinical practice for quick selection of right antibiotics to treat infectious diseases at the early but critical stage. However, currently available testing methods normally require growth of bacteria into colonies, which usually take more than two days to accomplish a task. They are, therefore, not satisfactory for practical needs that require fast answers. Moreover, these methods are not applicable for slow-growing bacteria, or samples containing sub-populations of slow- or non-growing bacteria which can resume growth after the antibiotic attack. To understand if and how the sub-population of slow-/non-growing bacteria causes failure in infection treatments, rASTs at the single cell level is required. To address these challenges, our project aims at developing a novel Silicon (Si) chip based all-electrical testing platform to achieve rAST at single cell level. The success of this project will potentially provide a low-cost and rapid ASTs platform for effective infection treatments. It could also help to accelerate the development of new antibiotic drugs in the pharmaceutical industry.

Duties: The applicant is expected to drive the bacteriological side of the project. Duties include general microbiology and molecular biology work in the laboratory as well as experimental work in the clean room facility with testing the devices being developed. Bioinformatic analyses of bacterial genomes to identify metabolic pathways are included. The project requires extensive knowledge about bacterial metabolism and physiology, so the duties include literature searches as well as oral presentations and writing/editing of scientific papers.

Qualifications: We are looking for highly-motivated applicants with a PhD degree in a microbiology, molecular biology or similar. The applicant's PhD degree must have been obtained no more than three years prior to the application date. However, periods of sick leave or parental leave are deductible from the three years period. The candidate is expected to be able to work independently and to have a strong interest in antibiotic resistance, tolerance and bacterial metabolism. In addition, the candidate is expected to take own initiatives as well as to collaborate with colleagues both within and outside of the research group. The position is in an international context so good oral and written communication skills in English are essential. Finally, significant weight will be given to personal suitability such as; analytical and organizational skills, personal maturity, ability to work with others, take initiatives, and to show good judgement.


-Documented expertise in microfluidics, cell trapping or microscopy is meriting

-Documented ability of work relating to bacterial metabolism is meriting
