Gianluca Gubbiotti is a researcher at the Perugia Institute of Materials of the Italian National Research Council (CNR), Italy. He received his PhD in materials science from the University of Camerino, Italy, in 1998. He has long-standing expertise in the study of fundamental and applied aspects of magnetization dynamics in magnetic nanostructures by Brillouin light scattering spectroscopy. He is also a leading expert in the study of the spin-wave band structure of planar and layered magnonic crystals. Dr. Gubbiotti has authored or co-authored about 200 peer-reviewed papers in international journals and 10 book chapters on spin waves in magnetic nanostructures. His main research interests are spin dynamics of thin and ultrathin magnetic films and multilayers, magnetic properties of arrays of magnetic dots and wires, Dzyaloshinskii–Moriya interaction, magnonic crystals, and hybrid magnonic heterostructures.
