Research Interests

My group’s research involves using resonant/non-resonant inelastic, elastic and time-resolved X-ray scattering methods to study the elementary collective phenomena in condensed matter. Topics of current interest include the roles of charge, spin, orbital and lattice excitations in high-temperature superconductors, strong electron-electron correlations, electron-phonon interactions, spin and charge ordering and quantum criticality in strong-correlated materials.
