Description

Diffraction pattern of disordered crystal are characterized by a rich presence of diffuse scattering between the Bragg reflections. No unified theory for the analysis and interpretation exist that would be comparable to direct structure determination techniques as applied to bragg reflection intensities.
The intention is to build a toolbox using maschine learning and deep learning techniques to :
- classify the distribution of diffuse scattering like but not exclusive (single maxima; linear rods; layers; curved features; etc)
- asses the building principles using aspects of molecular form factors etc

Please describe areas in which you would like to improve your knowledge / skills.

Experience in pattern recognition; parallel processing using GPUs, maschine learning

What is your expertise in computing and / or software development?

30+ years developing the DISCUS program suite. Fortran 2013; parallel processing using MPI

My current most burning research question, I like to find partners for, is:

Analysis of diffuse single crystal data for complex structures

Please describe your expertise/areas in which you would like to contribute / advise.

Analysis of disordered structures, simulation of disordered structures

What is your field and role?

Crystallography
Professor

In ErUM-Data, what kind of data are you dealing with?

3D intensity data from diffraction experiments

Please describe areas in which you can contribute to “data handling” teaching.

Extensive experience in processing of powder pattern for the powder PDF; Extensive experience with diffuse singel crystal data
