Confirmed Invited Speakers
Luca Brombal
Luca Brombal is a tenure track researcher at the Department of Physics of the University of Trieste and affiliated with the Italian National Institute for Nuclear Physics (INFN) working on advanced X-ray imaging techniques, with a focus on phase-contrast and spectral methods mainly using photon-counting detectors. His research addresses both laboratory and synchrotron-based implementations, including modulation-based phase-sensitive approaches for multimodal imaging and micro-CT. He leads the PEPI (Photon-counting Edge-illumination Phase-contrast Imaging) Laboratory, a compact system integrating spectral and phase-contrast, and contributes to the development of detectors, simulation tools, and reconstruction methods for quantitative imaging applications.
Jordi Carstens

Michela Esposito
Dr Michela Esposito is a Senior Research Fellow at University College London in the Advanced X-ray Imaging (AXIm) group, where she works on developing novel imaging techniques for x-ray microscopy.
With a background in Physics (BSc and MSc), Michela completed her PhD at the University of Surrey working on the development of large area CMOS sensors for biomedical applications. She then joined the University of Lincoln where she developed novel instrumentation for image-guided proton therapy, leading the development of a novel calorimeter for proton computed tomography.
Since joining AXIm, Michela worked on extending laboratory phase-based imaging techniques to microscopic length scales, leading to the development of a phase-based x-ray microscope for high content volumetric histology. Michela now leads MRC- funded research on applying phase-contrast imaging techniques to the development of novel cancer therapeutics.
Dominik John
Dominik John studied physics at the Technical University of Munich (B.Sc., 2017–2020) and continued with an M.Sc. in Biomedical Engineering and Medical Physics (2020–2022). From 2023 to 2026, he was a doctoral researcher working on X-ray-based 3D virtual histology and modulation-based microtomography in the group of Prof. Julia Herzen at TUM. In parallel, he held a position as researcher at Helmholtz-Zentrum Hereon (2023–2026), carrying out experiments at the P05 and P07 beamlines of PETRA III (Hamburg). From November 2024 to April 2025, he was a visiting researcher in the X-ray Imaging Group of Prof. Kaye Morgan and Prof. David Paganin at Monash University (Melbourne, Australia), with experiments at the MCT beamline of the Australian Synchrotron. He recently completed his doctorate at TUM in August 2026. In 2025, he received the FastForwardScience Young Scientist Award in Germany's largest science communication competition, for a video on making X-rays "colourful" through spectral X-ray imaging.

Martin Rongen
Martin Rongen is a Staff Scientist at the Erlangen Centre for Astroparticle Physics (ECAP). He earned his PhD in Physics from RWTH Aachen University in 2019 and subsequently held a postdoctoral position at JGU Mainz before joining ECAP in 2023 to pursue his habilitation. Throughout these years he has worked as an instrumentation specialist and calibration expert for the IceCube Neutrino Observatory. Since 2025, he coordinates the Technology Transfer Group at the chair of Prof. Stefan Funk, overseeing research and development in X-ray phase-contrast imaging and clinical dosimetry.
