I use geochemistry to investigate the roles of fluids and volatiles in geological processes stretching from the Earth's surface to the deep mantle. I am particularly interested in hydrothermal alteration, metasomatism/metamorphism and magmatism. The common link between these areas, and the aim of my recent research, has been to investigate the longterm exchange of volatiles between the Earth's surface and mantle reservoirs, stretching from the seafloor, through subduction zones and into the mantle. I participated in Expedition 360 of the International Ocean Discovery Program in 2016, to the slow-spreading Atlantis Bank core complex on the SW Indian Ridge, where I acted as shipboard geochemist and crossed the equator by boat for the first time. I have long standing interests in fluid inclusions as tiny recorders of past fluid activity and special interests in the halogen and noble gas groups of elements.

I moved to UQ in 2019 from the Australian National University where I was a continuing Fellow and had held an ARC Future Fellowship. Prior to that I had an ARC QEII Fellowship at the University of Melbourne (2008-2013) and postdoctoral appointments at the University of Melbourne (2004-2008) and the Geological Survey of Norway (2001-2003). I did my PhD at the University of Manchester (2001) and undergraduate studies in Geology at the University of Edinburgh (1996).

I am a volcano scientist with a passion for understanding how magmatic systems work. I develop high-resolution geochemical techniques to interrogate magmatic crystals and their carrier melts, providing a better understanding of past eruptions as a key for future activity. My team aims to constrain the drivers of volcanic eruptions and the processes leading to the accumulation of metals that are critical for the energy transition.

I joined UQ as a Lecturer in July 2016, after holding a postdoctoral fellowship at Trinity College Dublin. I undertook my postgraduate research in Spain and The Netherlands (Vrije Universiteit Amsterdam) and received my PhD from the University of Zaragoza in December 2013. I was born and raised by the sea, in San Sebastián, and I am fortunate to study a wide range of active and past volcanic systems in different tectonic settings around the world.
