Research Areas
Synthesis, patterning and microscopy of hard and hybrid nanostructures. Development and implementation of novel electron microscopy techniques for nanostructures, interfaces and defects in complex materials systems. Development of (cryo-)electron microscopy approach to "soft" and "hybrid" materials.

The Dravid group is actively involved in synthesis and characterization of nanostructured materials, with an emphasis on prudent use of emerging and novel electron beam techniques to problems of assembly, structure, microchemistry and dynamics of nanostructured systems. Dravid also directs the electron probe instrumentation center (EPIC) which is a multiuser facility for advanced electron microscopy research.

Broadly classifying "nanostructures" as those materials whose properties and phenomena are intimately linked to structural entities at the nanometer level, Dravid's group is involved in advanced TEM characterization of interfaces, defects and nanocrystals, while in another area his work involves synthesis and patterning (Figure 1a) of novel magnetic nanostructures such as encapsulated superparamagnetic (ESP) nanocrystals (Figure 1b) for bio-diagnostics and therapeutics.
