Thesis Subject: Machine Learning for the Real-Time Analysis of X-Ray Spectroscopy Data
X-ray spectroscopy is an indispensable tool for element-specific analysis in most fields of natural sciences. It gives access to a wealth of information regarding the structural parameters and electronic properties of materials.
Currently, mapping the experimental data to the various properties of materials relies on manual processing, i.e., every single spectrum is interactively analyzed by a scientist. However, with the ever-increasing acquisition rates allowed by the emergence of extremely brilliant light sources, such workflows will become unpractical.
You will join the Algorithms & Scientific Data Analysis (ADA) group and develop machine-learning techniques to make fast and accurate predictions of properties (e.g., coordination number, oxidation state, concentration, etc.) from X-ray spectroscopic data. Your objectives will be to:
The project will bring much-needed automation of the data analysis workflows for X-ray spectroscopy, enable non-expert users to make better use of their data, and make the techniques more accessible to an even larger scientific community and especially industry. All work will be carried out in close collaboration with the ESRF spectroscopy beamlines, in particular ID24 and ID26.
