Voller's central research interest is the development of numerical methods for solving moving boundary problems, i.e., problems where one of the domain boundaries is an unknown of the problem. The classic example is tracking the water/ice front during the melting of a glacier (The Stefan Problem). Moving boundaries, however, are found in many engineering and scientific disciplines and Voller's research is directed at many diverse problems including: the tracking of sediment shorelines, the growth of crystals, moisture infiltration into soil, contaminant uptake in stream beds, and the solidification of metals. To tackle these problems Voller's group has developed techniques that cut across available state of the art numerical methods, these include: finite element methods, control volume methods, deforming grid calculations, cellular automata, lattice Boltzmann, Mote Carlo, and particle methods.
