- 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.
