Scientific interests:

  • Preparative inorganic chemistry: development of innovative methods for synthesis of inorganic salts, oxides, solid solutions and composites;
  • Crystal chemistry of inorganic compounds;
  • Vibrational Spectroscopy (infrared and Raman spectroscopy): interpretation of vibrational spectra; factor group analysis; matrix spectroscopy; bonding interactions in solid state;
  • Synthesis, structure, spectroscopic and morphological characterization of polyanion intercalation materials as electrodes for lithium-ion and post lithium-ion batteries;
