Research Focus

Our group focuses on designing, synthesizing, and characterizing novel functional inorganic nanomaterials for emerging applications in renewable energy and biological systems. We are particularly interested in the optical and magnetic properties of transition metal ion doped semiconductor nanomaterials, selective surface functionalization of nanoparticles, and hybrid nanocomposites. We aim to answer the fundamental questions pertaining to the role of composition, band gap engineering, and assembly of semiconductor nanomaterials on their physical properties.
