Research Interests

Development of novel polarized x-ray techniques and instrumentation enabling studies of the interplay between structure and electronic structure (chiefly magnetism) in functional materials. Focus is on studies of element-specific magnetism exploiting x-ray dichroic effects. Depth-resolved/interfacial magnetism in layered nanostructures, site-specific magnetism in crystals, and local atomic structure are probed using a combination of polarized spectroscopy and scattering probes. Emphasis is on tunability with external stimulii, particularly high-pressure and magnetic fields. Research includes discovery of novel phenomena in magnetocalorics, permanent magnets, high Tc superconductors and other complex oxides (spinels, manganites, multiferroics, iridates).
