Career Research Highlights

My prime research goal is to quantify the physical controls on volcanic eruptive style. In particular, my research focuses on the fundamental role played by magmatic processes and properties at the mesoscopic scale: i.e. at the lengthscale of intra-magmatic bubbles and crystals; and how these processes interact to determine eruptive behaviour at the volcano scale. My ongoing research in this field includes laboratory and numerical investigation of:

  • the rheology of bubble- and particle-bearing magma,
  • the flow of volcanic gases through permeable magma,
  • Dynamics of strombolian eruptions
