The research topics of Olivier Fruchart concerns magnetism and spintronics of low-dimensional structures, with a special focus on magnetization dynamics of domain walls and other magnetization textures. He is concerned with fundamental processes, investigated in model systems for a better understanding. This led him to acquire expertise at the frontier of several areas : experimental and theoretical micromagnetism ; surface magnetism; epitaxial growth particularly for self-organization, chemical synthesis, and associated material science, and various magnetic microscopy techniques. His main current focus is fundamental aspects in magnetic nanowires or nanotubes, in the field of curvilinear and 3D nanomagnetism and spintronics.

Olivier Fruchart graduated from Ecole Normale Supérieure in Paris, and has been conducting research at Institut Néel and SPINTEC, in Grenoble. He is currently Deputy Director of SPINTEC, General Chair of the European School on Magnetism, and from July 2022 onwards President of the European Magnetism Association.
