Research Interests


The discipline of chemistry is concerned with the composition, behavior, structure, and properties of matter, as well as the changes it undergoes during chemical transformations. Disciplines within chemistry are traditionally grouped as inorganic, organic, physical and theoretical chemistry whereas many more exciting cross-disciplinary aspects such as materials chemistry have emerged in recent years. My research interests span solid state and structural chemistry, materials chemistry and related areas. In solid state and materials chemistry, my interests are in phenomena and properties exhibited by transition metal oxide systems, including magnetism, superconductivity, colossal magnetoresistance, electronic phase separation, metal-insulation transitions and multiferroicity.

Research Interests


Our group studies the structural, compositional and morphological aspects of heteroepitaxial growth and formation of self-assembled nanostructures using surface reconstructions, modifications and dislocation patterns as templates, using surface sensitive probes in ultra-high vacuum. We have studied several metal/semiconductor and metal/metal interfaces and of late embarked on the synthesis and characterization of semiconductor heterostructures and band-gap engineering of materials (III-nitride) of interest in Solid State Lighting, Full Spectrum Photovoltaics, Water Purifications, High Electron Mobility Transistors, etc.

Research Interests

Soft Condensed Matter


Our research focuses on soft condensed matter physics. A few examples of soft materials include colloidal suspensions, polymers, liquid crystals and bacteria. Soft materials comprise of mesoscopic structures, size ranging from nanometers to microns, held together by energies comparable to the ambient thermal energy. Weak external stimuli, of the order of the thermal energy, couple strongly to soft matter microstructure that in turn determines the macroscopic response. The above characteristics of soft materials are exploited in numerous applications that include ketchups, automotive lubricants and flexible e-ink displays. Understanding the structure-response relationship of soft materials is essential for identifying properties exclusive to this class of condensed matter and will directly impact the development of novel soft materials with tailor-made properties.

Research Interests

Physics and Chemistry of Nanomaterials

My research interests are focused on studying the chemistry and physics of nanomaterials, in particular, semiconducting nanocrystals or quantum dots. The interest in these quantum confined systems stems from the fact that these tiny fragments exhibit a wide range of properties that can be tuned by changing the size of the particles. In certain cases, these tiny particles are known to exhibit properties that are not observed in bulk materials. Doping these nanomaterials with small amounts of other transition metal atoms alters their properties and adds another dimension to this interesting world of nanomaterials. Understanding the mechanisms at work in these tiny systems can have very important implications in the areas of photovolatics, displays, biotagging and drug delivery, memory storage and optoelectronic devices. Fundamental research into the synthesis of these doped and undoped nanocrystals by various chemical routes, as well as studying and understanding the size dependent optical and magnetic properties of these materials will constitute the major research activity in this group.
