Research interests

  • dynamic behavior of surfaces and interfaces in different chemical environments
  • in situ and operando microscopy and spectroscopy: STM, AFM, SEM, TEM, XPS, NRIXS, XAFS, mass spectroscopy/gas chromatography
  • correlations between the morphology, elemental composition, chemical state, electronic properties and lattice dynamics of nanoscale materials and their catalytic activity and selectivity
