Expertise: I design numerical models for predicting the behaviour and understanding the uncertainties in the operation of nuclear reactor cores and other nuclear processing facilities. In particular I develop mathematical models to accurately predict neutron and gamma transport within nuclear reactors, and couple these to thermal hydraulic codes that model coolant flows and heat transfer within a core. I am particularly interested in analysing both current nuclear reactors as well as those due to be built within the UK in the coming years, in particular the boiling water reactors. I am also heavily involved in the design of new mathematical models …
