Research

My primary research interest is the study of various quantum condensed matter phenomena and energy storage materials. The study includes (but not limited to) correlated behavior of 5d iridates, crystal/magnetic structure analysis of iron based superconductors, manganties, lattice dynamics in thermoelectric materials, topological insulating materials, structural analysis of fuel cells and battery materials. The method of research involves the synthesis as well as characterization using Neutron/x-ray scattering, magnetization and resistivity and other complimentary techniques.
