My research focuses on understanding the novel physical properties, and collective electronic and magnetic behaviors in various quantum materials, such as strong spin-orbit coupled systems, unconventional superconductors, and quantum spin liquids. To do so, I make use of combined neutron and x-ray scattering techniques, including inelastic neutron scattering and resonant elastic/inelastic x-ray scattering, which are supported by multiple sample synthesis approaches such as traveling solvent floating zone, flux, and Bridgeman methods.
