Accomplishments

• Pioneered the use of graphite spectrometers, and dynamically bent sagittal focusing optics (IR-100 award and Patent).
• Discovered the x-ray resonant Raman and the resonant Auger effects.
• Designed beamlines X14A at the NSLS and 33-ID and 33-BM at the APS.
• Pioneered the use of anomalous x-ray scattering to determine local structure in crystalline solid solution alloys.
• Pioneered the use of anomalous x-ray scattering to determine the structure and chemical state of buried interfaces.
• Demonstration of resonant magnetic scattering to study magnetic phase transitions.
• Demonstrated that precision inelastic x-ray scattering measurements can be used to study band structure of materials.
• First successful multiple wavelength x-ray holography measurement.
• Measured colony orientation of high Tc superconducting tapes for development of high current density.
