Research interests

As a member of the Polymers and Industrial Mathematics (PIM) group, my main current research interests are in the field of thin-fim viscous fluid mechanics, with particular emphasis on the development of (possibly automated) asymptotic methods for both deriving and solving the spatio-temporal evolution equations arising in both industrial coating flows and ophthalmic flows.

Other industrially related research has been done under funded collaborations with: Dr Daniel Read (Maths, PIM) on computational linear rheology; Professor Peter Jimack (Computing) on fully adaptive finite-element methods for free-surface viscous flows; PPG Protective and Marine Coatings (industrial sponsors) on the modelling of fire-resistant properties of reactive intumescent protective coatings, and; Defence Research Agency (Fort Halstead) on the modelling of high-velocity impact phenomena.

As a former member of the now-disbanded Computational PDEs group, my other current research interests involve error analyses of numerical methods for solving Fredholm integral equations of the second kind, because many examples of these arise when modelling industrial problems. A full understanding of the errors incurred in such methods may enable improved techniques to be developed and implemented. For example, recent research on problems involving boundary singularities can provide an better insight into crack formation in elastostatics.
