Primary area of research is soft condensed matter physics, in particular, the structural determination of biologically relevant systems and their interactions through the use of appropriate scattering techniques (i.e. neutrons, x-rays and light).

Current interests include:

  • The development of spontaneously forming, functionalised unilamellar vesicles specifically targeted to delivering payloads to the brain.
  • The detailed structure of biofilms.
  • Atomic resolution neutron and x-ray holographies.
