Dr Meurig Gallagher is a Research Fellow in Applied Mathematics. Meurig's research concerns the utilisation of numerical and analytical techniques to solve problems relating to fluid dynamics. His work to date spans several aspects of fluid behaviour, from free surface flows to the stability of non-Newtonian fluids, and has recently found interest in modelling behaviours of biological fluids.
