PhD Position in Engineering the Microstructure of Bacterial Cellulose for Sustainable Applications

We are seeking a PhD candidate to work on an interdisciplinary project that uses soft matter physics and material science concepts to develop the next generation of architected bacterial cellulose for fundamental and sustainable applications.

Pressing challenges in climate change require the development of the next generation of renewable materials addressing cooling, CO2 capture and energy production. Bacterial cellulose is a very promising material to be used in a sustainable future because it is purer than plant-extracted cellulose and it is produced in a sustainable way. While this material has already showed promising applications in food, tissue engineering and energy, a fundamental physical understanding of its structural formation, as well as robust processing methods to control its structure across scales, are still missing.

The goal of this project is to develop novel methods to engineer the structure of bacterial cellulose at different length scales (nm-mm) and make functional materials for sustainable applications (such as heat insulators or filters). In particular, we will use the combination of bottom-up approaches (liquid crystal self-assembly and phase separation ) with top-down approaches (3D printing) to carefully control structural features at various length scales. We will then characterize a range of fascinating structure-function relationships of these biomaterials with various techniques. These include confocal microscopy, polarized optical microscopy, tensile tests and X-rays. Finally, we will collaborate with the Digital Building Technologies lab at the Department of Architecture at ETH to explore innovative integrations of biofabricated materials and sustainable buildings.

• You have a master’s degree in material science, physics, chemistry or mechanical engineering
• You also have prior experience with optical/confocal microscopy, soft (bio)materials and image analysis techniques
• You are curious, a good team player, and have a great motivation to learn and work independently at the forefront of sustainable materials
• You have excellent oral and written communication skills

• An open and collaborative research environment
• Access to and training in cutting-edge methodologies and instrumentation
• Possibilities to develop entrepreneural skills and training
