Areas of Research

Experimental studies of strongly correlated electron systems including high temperature superconducting copper oxide and iron pnictide based systems. Studies of novel magnetic phase behavior in complex oxide materials and quantum critical systems. Experiments probing non Fermi-liquid behavior in magnetic materials. Experimental methods primarily include utilizing neutron scattering and spectroscopic techniques for the study of spin/structural order and dynamics.
