RESEARCH INTERESTS

My research focuses primarily on the use of neutron (and X-ray) scattering techniques to investigate the ground state properties and the nature of phase transitions in strongly correlated systems. Strongly correlated systems are materials in which strong interactions exist among electrons, lattice vibrations (phonons) and spins. These interactions often lead to exotic ground states and efforts to understand such ground states, as well as the fundamental excitations out of them, make up a lively area of condensed matter physics research. Some examples of strongly correlated systems are the high-temperature cuprate superconductors, heavy fermion compounds, Kondo compounds and Mott insulators.
