My work lies in the field of inverse problems and mathematical imaging, particularly applied to image reconstruction and restoration of X-ray-based 3D/4D imaging techniques. At my current position I am doing generalized data processing for several imaging techniques, both in the design of reconstruction methods, arifact/misaligment corrections and in algorithmic implementations.
