Materials science and technology are our passion. With our cutting-edge research, Empa's around 1,100 employees make essential contributions to the well-being of society for a future worth living. Empa is a research institution of the ETH Domain.

The Biointerfaces Laboratory is offering a Postdoc position focused on the development of in vitro simulation models for performance evaluation of 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 primary focus of this position is to establish advanced in vitro simulation models for vascular grafts to assess the performance of nanoengineered antimicrobial and antifouling coatings. Key objectives include:

• Development of an in vitro model that mimics an in-vivo-like environment such as flow, medium, and temperature to ensure the translational potential of the coatings.
• Comparison of the established model with the standard lab models for evaluating coating stability, durability, and antimicrobial efficacy
• Integration of coating and biological performance data to guide optimization of multifunctional coatings.

Your profile

The candidate should have a PhD degree in Microbiology, Biotechnology, Biomedical Engineering, Materials Science, or a related discipline, with expertise relevant to antimicrobial materials and invitro testing. Key qualifications include:

• Proven ability to develop and apply complex in vitro or ex vivo test systems.
• Hands-on experience with microbial assays, biofilm models, and/or biomaterial characterization.
• Strong project management and communication skills, with the ability to contribute expertise in a collaborative setting.
• Fluency in written and spoken English.

We are looking for a highly motivated postdoctoral researcher who is eager to contribute to the translation of fundamental research into clinically relevant antimicrobial solutions.

Our offer

The Biointerfaces Laboratory is located in St. Gallen at the Swiss Federal Laboratories for Materials Science and Technology (Empa). Our team is highly interdisciplinary and international, providing an inspiring environment for high impact research. We have internal expertise in (micro)biology, chemistry, materials engineering, and ex vivo models, and we have strong collaborations with external academic, industrial, and clinical partners to ensure project success. Additionally, Empa offers outstanding infrastructure, career support, networking opportunities, and competitive salaries. The position is available from January 2026 or after negotiation, for an initial duration of two years with the possibility for extension.

We live a culture of inclusion and respect. We welcome all people who are interested in innovative, sustainable and meaningful activities - that's what counts.
