Short presentation
My main research area is experimental magnetism focusing on nanostructured, amorphous, frustrated and disordered materials. My work include the design and development of functional nanocompostite materials using sputtering, ion implantation and additive manufacturing techniques. The aim of my research is both to extract fundamental knowledge and to develop soft magnetic materials for applications in efficient electromechanical energy conversion.
