OFFER DESCRIPTION

Using today’s computing power and software packages it has become possible to analyze large and multidimensional experimental scattering data. The process of converting these data into useful scientific information, however, can be challenging.Popular machine learning models, such as artificial neural networks, have recently shown significant advantages in terms of speed over other computational methods that are usually employed to extract the essential parameters of the investigated systems [1,2].

Within the field of soft matter physics, our group studies the fundamental structural properties, particularly the growth process, of organic thin films [3]. In this context, we collect X-ray scattering data using highly specialized synchrotron beamlines, e.g. at the ESRF in Grenoble or at Petra III in Hamburg. Modern area detector technology allows us to record enormous amounts of complex data, however, usually data analysis remains the bottleneck for the scientific output.
