Job description: PhD Position - DNA-based Liquid Crystal Elastomers - Towards an artificial cytosceleton

Join us in exploring how the principles of soft matter and biomolecular self-organization can inspire the next generation of functional materials. Our research at the

Institute of Biological Information Processing - Biomacromolecular Systems and Processes (IBI-4)

combines physics, chemistry, and biology to understand the collective behaviour of biomacromolecules and to develop innovative liquid crystal elastomers with programmable mechanical properties. In this project, you will contribute to the fabrication and characterization of novel microscale liquid crystal elastomers using advanced microfluidic techniques and state-of-the-art microscopy and rheology. Your work will help uncover how rational design governs mechanical function, providing new insights for responsive materials with applications ranging from bioinspired actuators to model systems for cellular mechanics.

Your Job

As part of this project, you will fabricate and characterize novel microscale liquid crystal elastomers (micro-LCEs) based on charged microgels with tailored polymer network architectures. Your work will involve the production of micro-LCE particles using microfluidic techniques, followed by their structural and responsive characterization using microscopy and scattering techniques. You will investigate the influence of temperature and ionic strength on particle conformation and explore the mechanical properties through linear and non-linear rheological measurements on corresponding bulk polymer networks.

Your work will be supported by an international interdisciplinary research team.

Some of your specific tasks are in detail:

• Contribution to the optimization of material synthesis protocols
• Performing microscopy, scattering and rheology exepriments
• Analysis of experimental data
• Preparing scientific publications
• Participation in conferences in Germany and abroad to presenting your research results
• Exchange with internal and external as well as national and international project partners

Your Profile

• You hold a Masters degree in ideally physics, physical chemistry, biophysics or a related field with a specialization in soft matter science
• You have some experience in data analysis using standard software like Origin and in scientific programming
• Experimental experience with light scattering, microscopy and rheology is not mandatory but would be very helpful
• You speak and write proficiently in English, are communicative and enjoy working in an international team.
• You have good organizational skills and the ability to work independently
• You have a high degree commitment and a very reliable and conscientious style of working
• In the best case you are available not later than December 2026

Please feel free to apply for the position even if you do not have all the required skills and knowledge. We may be able to teach you missing skills during your induction.
