Understanding the interrelationship between structure and properties in semiconductors, superconductors, and magnetic materials and deformation behavior of solids. Current focus is on origins and reduction of threading dislocations in group III-nitride layers, microstructures of mixed III-nitride layers and how defects affect device behavior.
