Research Interests

• Material aging, compatibility, transformation, and degradation mechanisms and impact on performance.
• Phase transitions in materials under static and laser-driven dynamic compression.
• X-ray diffraction as a diagnostic for studying materials phase transitions and reactions in situ.
• Synthesis and structural and physical characterization of new metastable materials using non-traditional solid-state methodologies.
