Research interests

Experimental Condensed Matter Physics and Materials Science
      

My research interest is to discover new functional materials and to explore how the coupling between lattice, spin, orbital and charge degree of freedom drives the fantastic properties using various characterization techniques, with an emphasis on neutron scattering techniques. The functional materials I have been working include Topological semimetals, Fe-based superconductors, multiferroics, Ruthenate, magnetocaloric materials, thermoelectric materials, etc.
