Full-time
postgraduate degree
Posted 5d ago
~40 hrs/week
Responsibilities
The PhD student will establish 3D in vitro infection models to investigate bacterial survival and neutrophil interactions in fracture-related infections. They will identify immunomodulatory compounds and collaborate with biomaterials researchers to develop localized infection prevention strategies.
Requirements
A Master's degree in microbiology, immunology, or a related life science is required. Candidates should have practical experience in microbiology, cell culture, and immunological assays such as flow cytometry and microscopy.
Full job description
Short Description
This PhD position is part of the PREPARE project (Programmable Release of Prophylactic Antibacterial & Response Enhancing agents), a collaborative initiative between the Infection Biology and Biomedical Materials Focus Areas at the AO Research Institute Davos and CK CARE (Prof. Pierre Yves Mantel). The Ph.D. student will be formally affiliated with the University of Fribourg and will be co-supervised by Prof. Michael Walch, Department of Oncology, Microbiology and Immunology, Faculty of Science and Medicine at the University of Fribourg.
Fracture-related infection (FRI) remains a major clinical challenge despite current prophylactic strategies. Increasing evidence shows that early infection establishment is driven by rapid formation of Staphylococcus aureus microaggregates and transient impairment of neutrophil antibacterial function following trauma.
The PREPARE project aims to address this problem by:
Defining the earliest events enabling bacterial survival in the surgical field (aggregate formation, fibrin encapsulation, antibiotic tolerance)
Identifying small-molecule immunomodulators that enhance neutrophil antibacterial activity
Contributing to the development of next-generation responsive biomaterials for localized infection prevention
Start of work: Position will remain open until role is filled, preferred start by October 2026.
Duration: 4 years
Main Responsibilities
Establish and optimise advanced 3D in vitro infection models (e.g. staphylococcal abscess communities)
Investigate early events in infection establishment, including bacterial aggregation, fibrin encapsulation, and antibiotic tolerance
Characterise neutrophil–bacteria interactions, including phagocytosis, ROS production, and bacterial killing
Identify and evaluate immunomodulatory compounds that enhance neutrophil function
Perform cell culture and co-culture experiments using primary human neutrophils and bacterial pathogens
Apply advanced techniques including confocal microscopy, flow cytometry, and molecular assays
Analyse and interpret complex experimental datasets
Contribute to interdisciplinary collaboration with biomaterials researchers within the PREPARE project
Main Requirements
Master’s degree in microbiology, infection biology, immunology, or a related life science discipline
Practical experience in microbiology and/or host–pathogen interaction studies
Experience with cell culture and immunological assays (e.g. flow cytometry, microscopy)
Strong interest in infection biology, innate immunity, and translational research
Ability to design, plan, and execute experimental studies independently
Excellent communication skills in English
Motivation to work in a highly interdisciplinary and collaborative environment
Additional desirable skills:
Experience working with primary immune cells (especially neutrophils)
Familiarity with 3D cell culture or infection models
Knowledge of bacterial physiology, antibiotic tolerance, or biofilms
Experience with advanced imaging or transcriptomic approaches
Interest in translational research and biomaterials-based therapeutic strategies

Established 1959, AO Research Institute Davos (ARI) aims to:
• Contribute to high quality applied preclinical research and development (exploratory and translational) focused towards clinical applications/solutions.
• Investigate and improve the performance of surgical procedures, devices, and substances.
• Foster a close relationship with the AO medical community, academic societies, and universities.
• Provide research environment/support for AO clinicians.
All AO Research Institute Davos projects are applied preclinical research or applied preclinical development projects focused towards clinical applications. Definitions (within the applied research):
• Exploratory applied preclinical research is fundamental research, to solve major clinical problems over an extended timeframe (over ten years).
• Translational applied preclinical research aims at developing a clinical applicable result in around five years and builds upon the fundamental applied preclinical research. This research is usually not possible without the previous fundamental applied preclinical research.
