## Research interests

Most of my career has been spent working on hyperbolic systems of conservation laws, which are the equations that model the physics of compressible flow, non-linear elasticity, shallow water and many other phenomena. Since these equations are very difficult to solve analytically, much of my work has involved the development of numerical methods, in particular the development of an extremely general code which uses a hierarchical adaptive grid and modern upwind methods. This is able to solve pretty well any system of hyperbolic conservation laws very efficiently since the adaptive grid is able to resolve sharp features such as shocks, shear layers and reaction zones. The code is also able to multi-fluids and multi-phase flow. It has been implemented on distributed memory parallel machines using MPI. The generality of the code is demonstrated by the areas to which it has been applied, such as:

Astrophysical gas dynamics and magneto-gas dynamics (e.g. star formation, detonation waves in supernovae).

Detonation waves in industrial explosives.

Flames and detonation to deflagration transition in combustible mixtures.

Multi-phase flow of carbon dioxide. Microbial chemotaxis in groundwater.
