Prof Don Kearley received his PhD from the University of East Anglia, UK, worked at the Institut Laue-Langevin in Grenoble, France, became Chair of Radiation Physics at Delft University of Technology, the Netherlands, and is presently Senior Researcher in the Neutron Scattering Group at the Bragg Institute of ANSTO (Australian Nuclear Science and Technology Organization). He has a fair experience of most neutron-scattering techniques, particularly inelastic and quasielastic methods. Currently most of his work is in providing modelling support for the neutron scattering activities of scientists at the Bragg institute and elsewhere, which is usually in the form of understanding the underlying mechanism in function. Dr Vanessa Peterson is a Senior Research and Instrument Scientist at ANSTO (Australian Nuclear Science and Technology Organization). Her expertise includes structure and dynamics in chemistry and their relationship to properties in condensed matter materials including cement,porous coordination framework materials, and hydrogen storage materials. She has also great expertise in analyses techniques like Synchrotron/Laboratory X-Ray and Neutron Powder Diffraction, Rietveld analysis, Quasi-Elastic Neutron Scattering, Inelastic Neutron Scattering, and Single Crystal X-Ray Diffraction.
