My research is focusing on: 1. synthesis of new quantum materials; 2. the structural and spin dynamics of these materials.

Ph.D.2003/9-2008/7 Institute of Physics, Chinese Academy of Sciences,condensed matter physics
  Work Experience  
Postdoc. 2008/9-2012/9 Japan National Institute for Materials Science
Postdoc. 2012/9-2015/6 UK University of Oxford
Assistant Professor 2015/7-now China ShanghaiTech University
  Research Interest  
1. Exploration of new quantum materials, including unconventional superconductors, magnetic and functional materials.
2. Structural and spin dynamics in quantum materials.
For the synthesis of new quantum materials, we use both normal and high pressure methods which enable us an effective route toward the discovery of interesting materials. To proble the structural and spin dynamics through which to reveal the mechanism dominated the exotic properties, we also use many advanced techniques including synchrotron X-ray, neutron, moun spin-rotation, resonant inelastic X-ray scattering, etc. in addition to the basic measurements by means of normal X-ray diffraction, SQUID, PPMS, etc.
