The properties and performance of materials - whether physical or biological or hybrid - are dictated by complex atomic and nanoscale architecture and associated phenomena. Our research is geared towards not only their understanding but manipulation and tailoring to yield favorable response and behavior. Such materials include nanostructures, especially inorganic/organic hybrids, and phenomena often revolve around various defects and their dynamic behavior. Thus, the core theme in Dravid group is the paradigm for "Form-Function" and "Structure-Property" relationship in diverse materials; it spans fundamental and basic science of materials as well as their technological implications and applications.
