  3. – Teaching assistant of “Physics 1”(S.S.D. FIS/01) at the Department of Chemical, Biological, Pharmaceutical and Environmental Sciences.

Research activity: 
Competence: Experimental Physics (Structure of matter and Optical Physics) with main interests in Light scattering processes, elastic and inelastic; Raman spectroscopy of complex systems and semiconductor materials for Plasmonics and Photonics. Development of optical sensors.


  • Study of light transport phenomena in nanostructured disordered systems with short and long range correlations (fractal systems) and study of their optical properties: light field enhancement and interference effects in elastic and inelastic scattering regime (Raman scattering).
  • Study of nanostructured materials for Photonics and Plasmonics by optical spectroscopy and light scattering. Comprehension of field enhancement phenomena typical of optically resonant metallic nanostructures (SERS by nanoantennas). Development of SERS (Surface Enhanced Raman Scattering) sensors for high sensitive detection of biomolecules (on substrate or in liquid environment). Development of optical sensors compatible with silicon technology.
  • Study of morphological, structural and dynamic properties of a novel class of salts, Room temperature ionic Liquids (RTILs), and their binary mixtures. This study was performed by Infrared absorption, light scattering techniques (Raman scattering).


  • Research activity oriented on growth of new materials, as semiconductor oxides, metallic nano-aggregates and polymeric films by laser ablation techniques and on their characterization by optical spectroscopy.
  • Research in atom physics: “laser cooling” of Gallium neutral atoms and growth of organized Gallium nanostructures by laser manipulation of atoms (Atom Lithography). The study was also focused on the comprehension of atom-surface interaction and self-assembling phenomena of Gallium atoms.
  • Growth and development of nanostructured materials by means of Chemical Vapour Deposition (CVD) and Physical Vapour Deposition (PVD), optical lithography and etching techniques (dry and wet), study and characterization of thin films by Ellipsometry, Fourier Transform Infrared Spectroscopy, Raman Spectroscopy and Electron Microscopy (SEM and TEM).
