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).

New PhD scholarship in 2025: I have an open PhD position in my group with collaboration opportunities with government and industry partners (Check out this scholarship with this link).

I am a Senior Lecturer in Geochronology and Tectonics. I am also an Advance Queensland Industry Research Fellow working on using geochronology (and thermochronology) and micro-analysis to improve knowledge in geoscience related to critical minerals. This Fellowship project is a key activity in my research group and I am always looking for motivated students and ECRs to join this research. It is sponsored by Queensland State Government and in collaboration with leading companies in the critical minerals industry.

Here's my recent seminar on some of the work in my group: https://youtu.be/twNcLECCqPg?si=501qcfSA2mJdHxUh

Broadly speaking, my research advances fundamentals of Plate Tectonics, the unique and unifying theory for our home planet. My group uses a set of field, laboratory, and computational approaches to reveal the geologic history of modern and ancient plate boundaries, focusing on reconstructing the evolution of plate-margin mountains and basins. Such regions are among the most dynamic in the Earth system: their development alters regional and global climate, impacts biogeographic evolution, triggers earthquakes and other geologic hazards, and determines formation and distribution of natural resources such as critical minerals. I have been fortunate to work in some of the most rewarding areas for geologists, including the Himalaya-Tibetan Plateau, Central Andes, eastern Australia, New Zealand, and Pacific Islands. Check out some of my field photos here. I am the lead of UQ Thermochronology Lab. As an in-depth user of UQ RIF (Radiogenic Isotope Facility), I also work with laser ablation ICP-MS with recent work around laser ablation geochronology and geochemistry.
