Dr Roach's primary research interest is the application of inelastic neutron scattering to the characterisation of technologically important materials, with a special interest in nano-carbons and graphitic materials. He is responsible for the development of the 'Scatter' functionality within the GULP software; this functionality allows GULP users to generate simulated coherent, incoherent and total inelastic scattering function from lattice models, using both semi-empirical and DFT-based potentials.
Specific research interests include:
* The analysis and interpretation of inelastic neutron scattering data, especially poly-CINS data.
* Modelling and dynamics of a wide range of technologically important nano-materials.
* The study of hydrogen storage materials.
Dr Roach is Researcher Co-Investigator (with Prof. Keith Ross as PI) on two EPSRC funded projects in which he shares responsibility; the 3-year, £360k EP/G049130 (The dynamics of nanomaterials and light metal deuterides studied by means of coherent inelastic neutron scattering measurements and model simulations) and the new major £1.25m, 3 year consortium project EP/I003312 (Fundamentals of Current and Future uses of Nuclear Graphite), working with scientists and engineers from Manchester, Salford, Sussex, Leeds and Nottingham Univeristies.
Currently the only available methods of investigating the dynamics of nanomaterials are more or less limited to IR and Raman and density of states measurements using incoherent inelastic scattering. We have developed a methodol... more >>.
