PhD Student

In physics of soft condensed matter

Your tasks

The PhD student will develop experimental and data analysis techniques to infer the 3D organization of fluids under flow. This project is a collaboration among the Swiss Light Source SLS and the Swiss Spallation Neutron Source SINQ that aims to apply small angle scattering and grating interferometry techniques, as well as rheology, for measuring the structure of fluids. 

  • Develop mathematical models for the 3D scattering of soft matter under flow 
  • Collaborate with novel ideas for experiments at SINQ and SLS 
  • Optimize and develop data analysis pipelines 
  •  Analyse and publish results from scattering and imaging experiments

Your profile

  • Master degree in physics, mathematics or computer science 
  • Excellent knowledge of English 
  • Excellent programming skills (python) and affinity to statistics 
  • Interest in lab work, soft matter physics and large scale facility experiments 
  • Flexibility to travel and to perform beamtimes 
  • Solution-oriented work attitude is essential
