The goal of my research is to understand the transfer of volatile elements from the mantle to the surface via magma ascent and degassing. This involves a combination of fieldwork at active volcanoes, experimental and analytical petrology, and theoretical modelling:

  • Volcanic gas remote and in-situ sensing; I use a range of spectroscopic and other sensing equipment (OP-FTIR, UV-DOAS, electrochemical sensors, UV camera…) to characterise the gas emissions from volcanoes (e.g. Erebus, Villarrica, Turrialba, Merapi…) and understand the dynamics of active vs. passive degassing.
  • HP-HT ex- and in-situ experiments; I use experimental apparatus (IHPV/ piston cylinders/ controlled atmosphere furnace/ Paris-Edinburgh Press) increasingly in conjunction with synchrotron radiation sources (HP beamline at ESRF and SOLEIL) to study phase equilibria, volatile solubility and physical properties (density, viscosity) of magma at high pressure and temperature.
  • Melt inclusions and glass spectroscopy; I use laboratory and synchrotron-based analytical techniques (XANES/ ion probe/ x-ray micro-tomography/ Raman/ NMR/ FTIR/ LA-ICPMS/ EMP/ SEM) in natural and synthetic products to understand how the composition and structure of the liquid and solid phases behave during degassing.
