Specialist research areas

Complex Fluids:

 

Emulsions

    • magmas undergo unmixing into immiscible liquids - this impacts on mass transport in magma chambers and ultimately on the formation of ore deposits and the eruptive behaviour of volcanoes

Convection:

 

Buoyancy-driven instability

    • this is important in solidifying magma chambers

Convection in porous media

    • this is important in solidifying magma chambers

Drops and Bubbles:

 

Breakup/coalescence

    • immiscibility in the crystal mush on the margins of magma chambers - transport of bubbles and liquid droplets in a liquid matrix governs the behaviour of the overlying volcano

Geophysical Flows:

 

Magma and lava flow

    • magma chamber solidification processes; magma transport in dykes, sills and surface flows
