Prof Sritharan's research expertise are in the areas of experimental processing and characterization of ceramics and metallics with focus on (a) multiferroic ceramic thin films, (b) barrier layers and inerface phenomena, and (c) nanostructured magnetic materials. His current projects are in the development of mutliferroic materials with magnetoelectric coupling for applications in spintronics, Ru-based diffusion barrier layers for Cu metallization, interface interactions in electronic packages, and the effects of nanostructure on the magnetic properties.
