Research Interests

We use state-of-the-art spectroscopic methods, in particular neutron and photon (Raman, X-ray) scattering, to study the structure and dynamics of materials with strong electron correlations. Topics of current interest include mechanism of unconventional superconductivity, magnetism and orbital physics in transition-metal compounds, magnetic systems with geometric frustration, topological magnon band structures, etc.
