Single-cell analysis of antibiotic tolerance in mycobacteria

The Department of Biomedicine is a joint initiative of the University of Basel and the University Hospitals Basel. It unites basic and clinical scientists to advance our understanding of health and disease and to develop therapies for areas of unmet medical need. With over 70 research groups and 800 employees, the Department of Biomedicine is the largest department at the University, located across six sites in the city centre.

Your position

We are offering a PhD position in experimental microbiology to study antibiotic tolerance in Mycobacterium abscessus, one of the most challenging to treat bacterial pathogens. The position is part of a newly funded international consortium that brings together experts in mycobacterial genetics, high-throughput phenotyping, structural biology, and clinical research across Switzerland, Israel, Australia and the USA.

The project

Antibiotic treatments for M. abscessus fail in more than half of patients despite in vitro drug activity. A key reason is drug tolerance, the ability of bacteria to survive antibiotic exposure without classical resistance. Our lab (boecklab.com) has developed a large-scale live-cell imaging platform that tracks hundreds of millions of bacteria during antibiotic exposure, enabling systematic analysis of killing dynamics.

Your profile

MSc in molecular biology, microbiology, or a related discipline
Experience in microbiology or molecular biology
Interest in combining computational and experimental approaches
Strong motivation, scientific curiosity, and drive
Ability to work independently and as part of a team
Good communication skills in English

We offer you

A fully funded PhD position within a highly collaborative international consortium
Training in cutting-edge technologies, including high-content imaging and automation workflows
A project positioned to reshape how antibiotic efficacy is understood and measured
A dynamic, international research environment in Basel
Competitive salary and excellent quality of life in Switzerland
