Research interests
My research interest are centered on the investigation of new exotic quantum states in bulk materials using complementary spectroscopic techniques (Nuclear Magnetic Resonance, Muon Spin Relaxation and Inelastic Neutron Scattering). In particular, I focused on frustrated magnetic compounds (kagomé, triangular, pyrochlore) which may host a quantum spin liquid state and materials with strong spin-orbit coupling.
