Our research program encompasses a methodical search for new materials in single-crystal form, and a systematic effort to elucidate the underlying physics of these materials. Our group is equipped with (1) advanced techniques and comprehensive facilities to synthesize bulk single crystals of a wide range of materials, in particular, novel transition metal oxides and chalcogenides, and (2) a wide spectrum of tools for experimental studies of structural, transport, magnetic, thermal and dielectric properties as functions of chemical composition, temperature, magnetic field, and pressure. Measurements are often carried out at extreme conditions, i.e., ultralow temperatures, high magnetic fields and high pressures. We have also established broad collaborations with leading scientists in the US and around the world.

We have currently worked on the following groups of materials: Iridates, Ruthenates, Rhodates and 4d- and 5d-electron-based chalcogenides.
