Your tasks

• Develop and implement microfluidics for soft matter and scattering measurements 
• Analyze molecular structures in real-time using advanced techniques like small-angle neutron scattering SANS and flow-induced polarized-light imaging (birefringence) 
• Develop a novel experimental and simulation framework to explain, model, and control macromolecular structuring under extreme flow conditions 
• Contribute to a multimodal, multiscale model that links flow conditions to molecular structures and rheological properties 
• Publish scientific results in peer-reviewed journals and present findings at international conferences
• Support the broader development of novel experimental strategies at SINQ

Your profile

• PhD degree in physics, physical chemistry, materials science, or a related discipline 
• Advanced knowledge of rheology, fluid dynamics, and microfluidics to design and execute experiments simulating real-world conditions 
• Demonstrated interest in soft matter physics, rheology, or flow-based characterization techniques  
• Practical experience with neutron or X-ray scattering is an advantage 
• Willingness to travel and participate in international beamtime campaigns 
• Strong communication skills in English (spoken and written) 
• Experience with data integration and analysis to connect results from different methods (rheology, birefringence, scattering) into a single, comprehensive model 
• Independent, solution-oriented working style and interest in experimental research 
• Strong programming skills, particularly in Python
