Research Interests

Almost every new technological innovation depends heavily upon the discovery of new materials and new novel physical properties. The discovery of many extraordinary properties of transition-metal oxides (TMOs), such as high-Tc superconductivity, CMR effect, and multi-ferroelectric effect, or the so called "strongly correlated systems", has opened many new fields in condensed matter physics. Recently, new "quantum states of matter" are coming increasingly to the fore in modern condensed-matter physics. Two celebrated examples are topological insulator and quantum spin liquid. The understandings of the strongly correlated spin/orbital/lattice couplings and the quantum phase coherence in all these materials are not only of fundamental importance but also potentially useful for applications. My main research interests are to discovery new materials possessing abnormal physical properties, such as geometrically frustrated magnetism showing quantum spin behaviors, multiferroicity, orbital ordering, and metal-insulator transitions. The strategies are to grow single crystals of them, and study them by x-ray scattering, low temperature and high magnetic field measurements, and neutron scattering. We expect our studies will advance the understanding of strongly correlated systems and quantum matters. For full statement of research interests, see here.

Brief Vita

I obtained my Ph.D. in Physics in December 2005 from University of Texas at Austin with Prof. John B Goodenough. Then, I became a Postdoctoral Associate at National High Magnetic Field Lab/Florida Sate University with Prof. C. R. Wiebe. In August 2008, I obtained a position as assistant scholar/scientist in NHMFL. I became an Assistant Professor in the Physics Department at UTK in August 2012. For a full CV, including full publications record, see here.


For Prospective Students

A couple of positions are immediately available for highly motivated graduate and undergraduate students who are interested in growing single crystals of novel materials and study them with different techniques. If interested, please e-mail or call me.
