Research interests


Strong focus on electron microscopy and atomic force microscopy. The research interests are currently centred on the development and production of multiscale nanostructured metal matrix composites an on mechanical characterization at fine scales. Work has also been developed in the following fields: metal solidification and solid-state transformations, crystalline defects and properties of intermetallic compounds. The research activity depends exclusively on funding obtained through competitive calls and long standing collaborations.
