Current Research Interests
- Additive manufacturing of metals. We use synchrotron-based scattering and diffraction methods to investigate the microstructural and phase evolution of additively manufactured alloys to establish the fundamentally important processing, structure, and behavior relationship.
- Dynamics of complex fluids and advanced functional materials. We have developed a version of X-ray photon correlation spectroscopy (XPCS) in the ultra-small angle regime that is capable of elucidating the equilibrium dynamics of optically opaque, concentrated colloidal suspensions in both aqueous and nonaqueous environments, as well as slow, nonequilibrium dynamics in industrially important advanced functional materials such as self-repairing dental composites.
- Structure and microstructure characterization of advanced materials using scattering methods, ranging from segmented copolymers, nanoparticles, organic-inorganic gels, to alloys.
- Small angle X-ray scattering: including instrumentation, methodology development, algorithm development, and data analysis.
