Current Research

The primary objective of Dr. Shield’s research program is to understand and control the microstructural evolution of materials during processing. Rapid solidification processing is of particular interest, as are nanostructured functional materials. Recent work is directed in the general area of high energy permanent magnets and studying the interfacial effects in exchange spring and exchange bias systems. Characterization specialties include electron microscopy and x-ray scattering techniques.
