PhD Position in Bacteria and Materials Interactions
The Bacteria and Materials Interactions Group at the Biointerfaces Laboratory is offering a PhD position focused on development of nanoengineered antimicrobial coatings. This project aims to tackle the growing challenge of infections caused by resistant bacteria through designing innovative, non-toxic, and durable antimicrobial solutions. This highly interdisciplinary project will be conducted in collaboration with several Swiss hospitals, offering a potential translation of scientific advancements into practical applications.
Your tasks
The PhD research will focus on developing innovative multifunctional coatings with integrated antimicrobial properties. Key objectives include:
* Design and synthesis of multifunctional antimicrobial coatings.
* Materials and physicochemical characterization of the fabricated coatings.
* Exploration of how material properties influence bacterial viability and biofilm formation.
* Identification and elucidation of the modes of action of bacterial killing/repelling.
The research aims to provide fundamental insights into bacteria & material interactions and contribute to the creation of next-generation antimicrobial materials with clinical relevance.
Your profile
The candidate should hold a Master’s degree in Microbiology, Biotechnology, Materials Science, Bioengineering, or a related discipline, with a strong interest in antimicrobial materials and bacteria & surface interactions. Key qualifications include:
* Hands-on experience with microbiological methods, material characterization, or polymer/ nanoparticle/ hydrogel synthesis.
* Strong analytical and problem-solving skills with high scientific curiosity.
* Ability to work independently and in a collaborative, interdisciplinary environment.
* Excellent communication skills in English (both written and spoken).
We are seeking a motivated and enthusiastic PhD candidate who is eager to engage in cuttingedge research and contribute to the success of the project.
Our offer
The Biointerfaces Laboratory is located in St. Gallen at the Swiss Federal Laboratories for Materials Science and Technology (Empa).
