My research interests include:

  • Thermal neutron, x-ray, and laser-light scattering to investigate the structure, interactions, and phase behavior of self-assembled complex fluids
  • Small-angle neutron (SANS) and x-ray scattering (SAXS), neutron spin echo (NSE), dynamic light scattering (DLS)
  • Theoretical framework for mapping detailed structure of macromolecules, such as large proteins, by the combined use of NMR nuclear spin-manipulation techniques and polarized neutron scattering as a spin-dependent atomic probe

    I have coauthored the graduate-level textbook: Interactions of Photons and Neutrons with Matter, 2nd edition, S.H. Chen and M. Kotlarchyk (World Scientific, 2007)
