Biographical details

  • B.Sc.(Hons) 1981
  • Ph.D. 1986, University of Melbourne

Research interests

  • Ionic liquids
  • Rheology of self-assembly materials
  • Polymerisable and polymeric surfactants
  • Small-angle x-ray and neutron scattering (SAXS and SANS)
  • Emulsions
  • Surfactant self-assembly at interfaces

Our research is aimed at understanding the behaviour of amphiphilic compounds in bulk phases (solutions, liquid crystals, complex fluids), in colloidal systems (emulsions, foams, dispersions), and at interfaces. We have been pursuing a wide range of projects examining the structure and dynamics of bulk phases and dispersions using techniques including neutron and x-ray scattering (SANS and SAXS), optical microscopy, rheology and calorimetry, and interfacial structure by neutron reflectometry, atomic force microscopy, and surface force measurements. By combining these techniques we are discovering new structures formed when surface-active molecules adsorb at the solid/liquid interface or when complex fluids abut an interface, and use this to design new nanostructured materials.
