Research interests

keywords: phonons, phononic crystals, Brillouin spectroscopy, Finite Element Method

My research interests are mainly focused on studying the elastic and magnetic properties of materials of various types. I investigate experimentally (Brillouin spectroscopy) and theoretically (Finite Element Method) propagation of bulk and surface elastic waves in crystals and layered materials. By using Dynamic Mechanical Analysis, I study elastic properties of bones. I also investigate spin waves propagation in magnetic materials by Brillouin spectroscopy.
