Coherence-Based X-ray Microscopy: Automated Tuning and Uncertainty Quantification
Supervisors: Prof. Christian Schroer (DESY, UHH), Dr. Johannes Hagemann (DESY), Prof. Martin Burger (DESY, UHH) 

Sebastian studied Technomathematics at the Hamburg University of Technology and the University of Hamburg. His Master’s thesis entitled “Motion Corrected Image Reconstruction in Tomography” was supervised by Martin Burger. In this thesis, he proposed and analyzed a model that accounts for motions - such as deformations, translations, and rotations - during CT scans.
His PhD project focuses on another inverse problem, the phase problem. It arises in coherent lensless microscopy, where image reconstruction relies on algorithms that depend on various parameters. Since the best parameter choice varies for each experimental setup, reducing the need for manual fine-tuning is a key project challenge. It opens up the perspective for broader applicability. Another aspect is quantifying the uncertainty of the reconstructed results, providing an estimate of their reliability.
