Research Interests

There is no doubt that properties and performance of materials are dictated by complex atomic and nanoscale features and phenomena. Our research is geared towards not only their understanding but manipulation as well. Such phenomena include nanostructured materials- especially inorganic/organic hybrids, and various defects in materials.

On one front, we are investigating the synthesis, patterning and characterization of nanostructured materials such as metal/alloy nanocrystals, biomolecular nanopatterns (DNA/proteins), interfaces between inorganic nanostructures and biomolecules, etc. These structures possess unique and novel morphologies and chemistry, and their electronic structure also depends on size and shape. We are exploring applications of such structures, including drug delivery, bio-diagnostics and bio-chem sensing.

We are also involved in atomic-scale structure-property relationship for internal interfaces, domains and mosaics. In a large number of material systems, such as electroceramics, semiconductors, superlattices, and structural composites, the property and performance of the bulk material are intimately connected to the structure, chemistry, and electronic structure of interfaces.

The philosophy of our approach is based on the sound fundamental foundation of complex phenomena, the liberal use of advanced instrumentation and techniques and the quest for proof-of-concepts for devices as well.
