LINXS Director and Core Group leader for the Imaging thematic. Associate professor at the Dept. of Solid Mechanics at the Faculty of Engineering (LTH), where he is also in charge of the 4D-Imaging Lab x-ray tomography facility. Came to Sweden in 2011 after moving from Laboratoire 3R in Grenoble, France.
Joined the Division of Solid Mechanics in May 2011 where he is a Senior Lecturer working mostly with experimental mechanics. Stephen has a degree and PhD in Geophysics (from Leeds, UK) and after a Postdoctoral position in 4D seismic imaging at Heriot-Watt University in Edinburgh he moved to Laboratoire 3SR in Grenoble, France, to work on experimental geomechanics (with a Marie-Curie individual Fellowship). Stephen was subsequently recruited as a "Chargé de Recherche" (permanent researcher) with the CNRS (the French national research agency). After 8.5 years in Grenoble, Stephen moved to Lund to join the Division of Solid Mechanics at LTH and for his first 4 years in Lund was also 25% with ESS. He has been very much involved in both the ESS and MAXIV projects. Stephen now works with a wide range of experimental methods, including extensively with x-rays and neutrons, to investigate deformation mechanisms in materials including the micro-scale origins of deformation and coupled processes. Key tools in his work include full-field measurements (2D and 3D-volumetric) to characterise deformation mechanisms: x-ray, neutron and ultrasonic tomographies; digital image correlation and analysis; 3D x-ray and neutron diffraction.
