Luis Palacio with Small Angle X-ray Scattering
Graduate student Luis Palacio measuring biological samples with Small Angle X-Ray Scattering (SAXS)


Work in progress involves:

  • The use of Nuclear Magnetic Resonance (NMR) to study structure-function relationships in biological macromolecules (Rao).
  • The use of NMR and to study protein structure and dynamics (Kemple).
  • Electron Paramagnetic Resonance (Kemple) is applied to investigate the effect of free radicals in biological processes.
  • Solid state NMR is used to study biological membranes (Wassall).
  • The structure and function of biological membranes is also investigated by X-ray scattering and ion transport (Petrache).


  • Research is performed using computer modeling and simulations of the physical properties of biological macromolecules (Betancourt), and elementary processes in biological systems (Rader).
  • There is also ongoing work in modeling the response of cells to cryopreservation (Kleinhans) and modeling membrane channels (Petrache).
