Fabien L ́eonard is a research associate at the Henry Moseley X-ray Imaging Facility at the University of Manchester. His research focuses on understanding the potential and limitations of X-ray computed tomography (XCT) systems and dimensional measurements, as well as developing new 3D measurement techniques for advanced microstructural characterization of materials. Some specific areas of research include verification of XCT system metrological performance, understanding XCT porosity measurements in composites through collaboration with the National Physical Laboratory, and using XCT to characterize defects in materials like composites, cement, and reactor pressure vessel steel.
