Background
I am a physical chemist specialising in solid propellant chemistry; investigating the material science and chemical properties of polymer/binders and explosive crystals to validate thermo-mechanical-chemical ageing models.
Qualifications: Member of the Royal Society of Chemistry. BSc in Chemistry and MSc in Surface Science and Catalysis, Liverpool University. PhD in Heterogeneous Catalysis from Department of Chemistry, Cardiff University.
Current activities
My main research interest is in life assessment and manufacture of propellants. I led a research team focused on all aspects of thermo-chemicial ageing, manufacture and processing of nitrocellulose. Current and recent projects include "Nitrocellulose degrees of freedom -towards an improved nitrocellulose specification
for rocket propellants, Ageing mechanism investigation of nitrocellulose containing PBXs, and Resonant Acoustic Mixing (RAM) of propellants and explosives.
My teaching interests are in gun and rocket propellants, chemical stability and compatibility, explosive science and technology, analytical chemistry and forensic science.
