My research focuses on extending the applicability of X-ray scattering and imaging techniques toward high resolution and specificity when characterizing statistically relevant ensembles, increasing dose efficiency, i.e., reducing sample consumption, and accessing transient states in operando. Starting from a fundamental understanding of the processes of X-ray scattering, propagation, and detection, experiments characteristically use and—if necessary—trigger the development of state-of-the-art instrumentation. Of particular interest is data and image analysis that is firmly underpinned by detection and estimation theory.
X-ray ptychography Characteristic for ptychography is its combination of high sensitivity and specificity with high spatial resolution and dose efficiency. The research goal encompasses development of the technique and pushing the envelope of what imaging capabilities are possible as well as turning ptychography into a technique that is useful for and usable by non-specialists.
High-brilliance applications of small-angle X-ray scattering: Small-angle X-ray scattering at a highly brilliant source with modern detectors enables measurements from small volumes, e.g., spatially resolved for imaging applications, with high time resolution for dynamics characterization, or with a combination of these properties and demands.
Management of the cSAXS beamline: Operation and development of the cSAXS beamline has the goal to provide a state-of-the-art facility for the Swiss and international user communities. We conduct instrumental, methodological, and analytical developments in order to maintain the beamline’s position as one of the premier facilities worldwide for coherent diffractive imaging and high-brilliance applications of small-angle X-ray scattering.
