Biography

Research Interests

• X-ray and synchrotron-based
characterization of
materials: Development and
application of advanced X-ray
scattering, imaging, and spectroscopy
techniques for probing microstructure,
electronic structure, and dynamic
processes in engineered and
nanostructured materials.
• High Explosives and Detonation
physics: Experimental investigations
into chemical, mesoscale, and
microscopic phenomena in high
explosives. Kinetics and mechanisms of
particulate, nanodiamond, and other
product formation and evolution during
detonation.
• Surface and interface science: X-ray
photoelectron and x-ray absorption
spectroscopies for electronic structure
of surfaces, molecular systems, and
nanomaterials
