My group investigates the structure and dynamics of quantum materials by spectroscopic and scattering techniques. Topics of particular current interest include the interplay between charge, orbital, and spin degrees of freedom in transition metal oxides, the mechanism of high-temperature superconductivity, and the control of electronic phase behavior in metal-oxide heterostructures and superlattices. Research in our group begins with the synthesis of high-quality single crystals and epitaxial thin films and multilayers, and includes a broad portfolio of experimental techniques such as elastic and inelastic x-ray and neutron scattering, neutron spin-echo spectroscopy, Raman scattering, and wide-band spectral ellipsometry. Our group also operates several beamlines at neutron and synchrotron facilities. The interpretation of experimental data and development of new ideas involves close collaboration with theorists, both inside and outside our group.
