| Areas of expertise | My current research focuses on multiphase magma rheology, in particular on the influence of crystals on the flow behaviour of a Newtonian liquid. Understanding the rheological properties of magma is of vital importance in physical volcanology, as the viscosity of magma can vary by several orders of magnitude and thus can play a decisive role in determining the eruptive style of a volcano. The existence of a crystal phase in a magma considerably influences its bulk viscosity and may introduce different kinds of non-Newtonian phenomena. To investigate these influences I am performing rheological experiments on magma-analogue samples, i.e. suspensions of different types of particles in a Newtonian liquid such as silicone oil. |
