My research interests center on understanding the strongly correlated electron phenomena in novel quantum materials, including but not limited to Diluted magnetic semiconductors (DMSs), Topological magnets and Superconductors (SCs).

In collaboration with TRIUMF and PSI, i primarily apply muon spin rotation/relaxation (μSR), together with neutron scattering, a.c susceptibility, electron spin resonance, to the study of local magnetic and electronic properties of these materials.
