• Pioneered the use of graphite spectrometers, and dynamically bent sagittal focusing optics(IR100 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.
