Steve Joël Gaudez

Dr. Steve Joël Gaudez is a Researcher at the Paul Scherrer Institute (PSI) in Villigen, Switzerland, affiliated with the Center for Photon Science and Laboratory for Condensed Matter. His work focuses on experimental and numerical analysis of microstructural evolution in metallic alloys under thermal and additive manufacturing processes.

His academic background includes:

• PhD from Université de Lorraine (Microstructures et contraintes group, Institut Jean Lamour) investigating microstructural evolution during tempering of martensite/nanobainite via synchrotron/TEM and numerical modeling
• Postdoctoral research at École polytechnique's Laboratoire de mécanique des solides studying phase transformations in alloys during additive manufacturing

Dr. Gaudez specializes in advanced materials characterization techniques, particularly in situ high-energy synchrotron diffraction and transmission electron microscopy. His research bridges fundamental metallurgy with industrial applications in steel processing and metal additive manufacturing, examining dislocation dynamics, precipitation kinetics, and phase transformation mechanisms at microstructural scales. Current projects emphasize real-time observation of microstructure evolution during 3D printing processes.

His recent publications demonstrate a cohesive research trajectory centered on additive manufacturing metallurgy and phase transformation kinetics in steels. The 2023 Additive Manufacturing paper reveals dislocation evolution during 3D printing using reciprocal space mapping, while the 2022 Materials Characterization study details martensite/nanobainite transformations via synchrotron diffraction. Both works exemplify his integrated approach combining experimental synchrotron methods with computational modeling.
