Research Interests

  • Physics of complex electron systems; strongly correlated transition metal oxides (colossal magnetoresitive manganites, cuprate high temperature superconductors, cobalt oxides), Fe-based high temperature superconductors, binary oxides (VOx, V2O3, EuO, CrO)
  • Physics of novel materials and novel materials characterization methodology; Materials for energy storage (cobaltites, delafossites, co-doped TiO2), and technological applications such as sensors, electronics, and displays (transparent conducting oxides)
  • Properties, growth, and characterization of low dimensional materials, nanostructures, surfaces and interfaces in materials of technological relevance
  • Light-matter interaction and physics of the fundamental processes concerning the use and development of soft-x-ray spectroscopies techniques; high-resolution angle-resolved photoemission spectroscopy (ARPES), core level photoemission spectroscopy, x-ray absorption spectroscopy (XAS), soft x-ray emission spectroscopy (XES) and inelastic x-ray scattering (RIXS); development of advanced scientific instrumentation for x-ray spectroscopies
  • Atomic, electronic, magnetic and orbital dynamics in complex electron systems; sub-picoseconds temporal dynamics of different degrees of freedom in complex electron systems; phase transitions.
