Tilo Baumbach
Tilo Baumbach is professor of experimental physics at the Karlsruhe Institute of Technology (KIT). He received his PhD for research in semiconductor physics at the University of Leipzig, worked as a scientist in the inelastic neutron spectroscopy group at the Institute Laue Langevin in Grenoble and later moved to applied and industrial research and development at the Fraunhofer Institute for Non-Destructive Testing in Dresden, where he used X-ray scattering, diffraction and imaging techniques.

Together with his PhD students, he established the techniques of full-field rocking curve imaging and synchrotron radiation computed laminography. Together with his groups, he designed diffraction and imaging beamlines, experimental stations, and in situ instrumentation, which they operate at synchrotron facilities (ESRF, KIT Light Source, PETRA III) and laboratory sources for applications in nanoscience, materials research and, increasingly, life sciences. Tilo Baumbach became head of the Fraunhofer IZFP branch institute in Dresden in 1999, director of ANKA (today KIT Light Source) in 2004, and is now head of the Institute for Photon Science and Synchrotron Radiation (IPS) at KIT.

Kaye Morgan
Prof Kaye Morgan is a physicist based at Monash University in Australia, working on new methods of x-ray imaging and applying these methods in biomedical research collaborations. Many of these applications have required high-speed imaging to capture biological function and avoid motion blur, and as a result, her group has focused on developing methods of x-ray phase and dark-field imaging that minimise the number of required exposures. This includes propagation-based imaging and some of the earliest work in speckle-tracking and single-grid imaging. Her experimental program has used conventional x-ray sources, the Munich Compact Light Source, and synchrotron sources, both around the world and across the road from Monash at the Australian Synchrotron. Her research program has been supported by a series of fellowships from the Australian Research Council (ARC), Veski, and the Technical University of Munich Institute for Advanced Studies, and project funding from ARC and the National Health and Medical Research Council.

Vittorio Di Trapani
Originally from Palermo (Italy), Dr. Di Trapani completed a bachelor’s degree in Physics (2015) and a Master’s degree in Medical Physics (2017) at the University of Pisa (Italy). His Master’s thesis concerned the characterization of a system for propagation based system for breast CT with synchrotron radiation implemented within the SYRMA-3D collaboration at the SYRMEP beamline of the Elettra synchrotron (Trieste, Italy). In 2017, he started a PhD in Experimental Physics at the University of Siena (Italy). His Ph.D. project focused on the implementation of two state-of-the-art acquisition systems for spectral imaging applications: (i) a laboratory setup for spectral micro-CT with an energy-resolving photon-counting detector, and (ii) a setup for K-edge imaging with bent-Laue optics with synchrotron sources. As part of his Ph.D. program, he spent six months as a visiting researcher at the University of Saskatchewan (Saskatoon, Canada), under the supervision of Prof. D. Chapman, working on the development of acquisition procedures and reconstruction algorithms tailored for spectral imaging with bent-Laue crystals. After defending his Ph.D. thesis, in July 2021 he joined the S-BaXIT project (ERC consolidator grant project led by Prof. P. Thibault) as a Postdoctoral Fellow. In the framework of the project, he worked on the design and implementation of a new laboratory facility for X-ray imaging (tomography, spectral imaging, propagation-based imaging, and speckle-based imaging) hosted by the Elettra Synchrotron. His main interests include X-ray detectors, spectral imaging applications, and the development of phase contrast techniques.

Tim Salditt
Tim Salditt is professor of experimental physics at the Institute for X-ray Physics of the University of Göttingen. He studied physics in Munich and Grenoble, and received his Ph.D. in 1995 for research in kinetic growth of surfaces and interfaces, which he studied by diffuse X-ray scattering and non-specular reflectivity with Hans Peisl at the University of Munich. He then moved his focus to biophysics, using the newly developed approaches for interface-sensitive scattering to study fluctuations in oriented lipid membranes. In his postdoctoral work with Cyrus Safinya in Santa Barbara, he worked on the structure and interactions of lipid/DNA complexes. Driven by the motivation to study biomolecular assemblies also in the hierarchical and complex functional environment of cells, he developed X-ray waveguide optics for nanoscale holographic imaging and tomography. With his group, he has designed a synchrotron radiation instrument, which they operate at the PETRAIII storage ring, together with DESY. Using a combination of diffraction with micro- and nano-focused beams as well as holographic imaging and tomography, they can now study biomolecular assemblies and biological matter, from the molecular level to biological cells and tissues. Recently, they also got increasingly involved with translating phase contrast tomography from synchrotron to laboratory instrumentation, more amenable for biomedical research groups. They push the limits in X-ray optics, including focusing, wave-front control, coherence, phase retrieval, reconstruction algorithms, information theory and image processing in order to get a maximum of information from a minimum of photons, Tim Salditt has been spokesperson of the collaborative research center Nanoscale Photonic Imaging for 12 years, and is a principle investigator of the DFG Center for Excellence Multi-Scale Bioimaging: from molecular machines to networks of excitable cells. He is a member of the Academy of Science in Göttingen, and of the DESY scientific advisory committee.
