Your Job:

Many technologically important material properties are closely related to disorder and short-range structural correlations. Diffuse scattering observed in a diffraction experiment on crystalline materials contains the information on dynamic and static disorder. Relating this information to the underlying structural disorder is a challenging task, particularly in the case of single crystal diffraction data where the information extends towards 3-d space. Machine learning offers promising approaches for the solution of complex problems of disorder, ultimately aiming at general and automated workflow for the analysis of single-crystal diffuse scattering. In this project, you will have the opportunity to contribute towards reaching this challenging aim.

Your tasks include:

• Deducing numerous models of structural disorder based on the periodic average structure, crystal chemistry, and complementary information
  
• Generation of a dataset to train ML models
  
• Simulation of the corresponding diffraction patterns and comparison to experimental data of a prototypic compound
  
• Develop a generalized machine learning based workflow for the interpretation of diffuse scattering

Your Profile:

• Completed Master`s degree in crystallography, material science, physics, chemistry, or a related field
  
• You have an interest in scattering methods, solid-state materials and ideally also knowledge in the field of programming, maybe even machine learning and artificial intelligence
  
• Prior knowledge of machine learning is not required, but considered an asset
  
• You have an independent and responsible way of working, commitment, high degree of teamwork, as well as enjoyment of cooperative collaboration
  
• Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the CEFR)
