The Complex Materials group at ETH Zurich translates the science of materials processing into societally impactful technologies through student entrepreneurship and interdisciplinary collaboration.

For this research projectin partnership with the Federal University of São Carlos (Brazil), we are looking for a:PhD candidate (100%) starting in April 2026 or upon agreement.

Growing concerns about the environmental impact of human activities have driven a strong demand for replacing synthetic functional materials with sustainable, naturally derived alternatives. Because of their renewable, biodegradable, and biocompatible nature, polysaccharidesoffer exciting opportunities for the development of next-generation functional materials.

ThisPhD projectcombines materials science and microbiology to explore how microorganisms can be used to produce high-performance biopolymers.The scalability and non-seasonality of this process will enablethe sustainable manufacturing ofbiopolymerfilaments, films and 3D structuresusing water-based processing methods.

To accomplish these objectives, we aim to bridge key knowledge gaps, particularly in understanding the processes that stimulate the productionof the polymersbymicrobialcells, as well as the chemical, structural, and mechanical properties ofthe produced fibers.

• The successful candidatewill conduct fundamental research on theproduction and extraction of microbial polymerfibersfollowing the state-of-the-art parameters and on the preparation of fiber bundles, films and polymer composites for future applications in different materials fields
• In collaboration with an interdisciplinary research team, thecandidate will have access to comprehensivescientific expertise for chemical and microbiological analyses, selection of promisingmicrobialstrains, biotechnological process parameter control, as well as material preparation and characterizationtechniques

We are seeking a highly motivated candidate with:

• Master’s degree inmaterial science/engineering,polymer chemistry, microbiology or closely related fields
• Proficiency in English is mandatory, both spoken and written
• Good interpersonal skills and the ability to thrive in a diverse, multidisciplinary environment

• Your job with impact: Become part of ETH Zurich, which not only supports your professional development, but also actively contributes to positive change in society
• Fully funded position with competitive salary according to ETH standards
• Interdisciplinary and international research environment
• You can expect numerous benefits, such as public transport season tickets and car sharing, a wide range of sports offered by the ASVZ, childcare and attractive pension benefits

We look forward to receiving your online application with the following documents:

• Curriculum vitae
• A complete academic transcript including undergraduate and graduate courses
• Copies of diploma/certificates
• Contact information of 2-3 referees
• A short description of research interests

Please note that we exclusively accept applications submitted through our online application portal. Applications via email or postal services will not be considered.
