Research Interests

My group’s research involves the use of state-of-the-art scattering methods, in particular neutron and photon (Raman, X-ray) scattering, to study the structure and dynamics of materials with electron correlations and novel quasiparticle excitations. Topics of current interest include mechanism of high-temperature superconductivity in copper- and iron-based materials, phenomenology and mechanism of charge order in metals and insulators, spin-orbital physics in transition-metal compounds, frustrated quantum magnets, and band topology of bosonic excitations in crystalline materials.
