My research focuses on the design, growth, and characterization of novel materials with unusual electrical, magnetic, thermal properties.  My work involves rational synthesis of novel materials, mainly in single crystal form, and investigation of the structure-function relationships. The goal is to understand how to design new materials with desired functionalities. Recent projects include: (1) Emergent phenomena in 4d/5d transition metal oxides arising from the competition between comparable energy scales, (2) CDW and superconductivity, and (3) High entropy oxides.
