Our research efforts focus on the microscope structure and dynamics of condensed matter using x-ray and neutron scattering techniques. Areas of study include the following:

  • Collective Excitations in Confined Quantum Liquids
  • Momentum Distribution of Hydrogen on Surfaces
  • Microscopic Structure of Confined Solids
  • Wetting on Nonstructural Surfaces
  • Dynamics of Hydrogen in Reduced Dimensionality
  • Hydrogen Storage Materials
These studies make extensive use of neutron and x-ray facilities both in the United States and Europe, as well as local facilities at Indiana University . Our research group is also involved in operating and constructing state of the art instrumentation. These efforts include:
  • Operation of Beamline X-18A at the National Synchrotron Light Source at Brookhaven National Lab
  • Construction of the Cold Neutron Chopper Spectrometer at the Spallation Neutron Source
  • Formation of the Neutron Education and Training Institution for the development of advanced Instrumentation
