Research Focus:
Synchrotron radiation applications

Research Interests

The focus of my research is the development and application of synchrotron x-ray microanalysis instrumentation and methods for trace element quantification using the x-ray fluorescence microprobe and chemical speciation determinations using x-ray absorption fine structure spectroscopy. Research problems include the chemical evolution of primitive extraterrestrial materials, e.g., interplanetary dust particles, comet dust, meteorites; speciation and mobility of toxic and radioactive species in the contaminated soils; and direct determination of the oxidation states of minerals and glasses.
