My research focuses on economic geology, structural geology and tectonics, with an emphasis on mineral systems, exploration targeting, ore-body characterisation, geological mapping, and the structural, metamorphic, magmatic and tectonic controls on mineralisation. I am particularly interested in how deformation, magmatism, metamorphism, basin evolution and hydrothermal fluid flow interact to form, modify and preserve mineral deposits.

I work across a broad range of commodities and mineral systems, including lode gold, IOCG, SEDEX, sediment-hosted Cu-Zn-Pb-Ag systems, porphyry Cu-Au systems, epithermal Au-Ag-Te systems, manganese, chromitite, ultramafic-hosted Ni-Co-Sc-Cr mineralisation, REE-Nb-Ta systems, indium-bearing Sn-polymetallic systems, and critical-minerals projects.

I am Associate Professor in Economic Geology at James Cook University, Head of the Economic Geology Research Centre, and Director of JCU’s Critical Minerals Trailblazer. These leadership roles are strongly industry-facing and focus on building partnerships between JCU, government and the resources sector to support mineral exploration, ore-body knowledge, critical-minerals discovery, technology development, professional training and workforce growth.

Through EGRU and the Critical Minerals Trailblazer, I work with industry and government partners to develop applied research projects that address real exploration and mining challenges. These projects aim to improve discovery, support ore-body characterisation, accelerate project development, and increase competitiveness and value creation for the resources sector.

A major strength of my work is the integration of academic research with direct industry experience. I have worked extensively with mining and exploration companies, including as an embedded researcher with Geita Gold Mine, where I contributed to exploration strategy, target generation, geological mapping, exploration-database design, QA/QC, training of exploration geologists, and the development of integrated geological and exploration models. My current and past projects have involved collaboration with major mining companies, junior explorers, geological surveys, government agencies and international mining operations.

My current research areas include:

• The Proterozoic Mount Isa region of northern Queensland, where my research focuses on Cu, SEDEX, IOCG, Zn-Pb-Ag and critical-minerals systems, as well as the structural, metamorphic, magmatic and tectonic evolution of the Mount Isa Inlier. This work includes ore-deposit characterisation, mineral chemistry, isotope vectoring, geochronology, seismic interpretation, geophysics, geochemistry and regional metallogenic synthesis.
• Northeast Queensland, where I work on critical-metals mineralisation, magmatic fertility, ultramafic-hosted Ni-Co-Sc-Cr potential, indium-bearing mineral systems, porphyry potential, and the development of a comprehensive tectonic and metallogenic framework for the region.
• The Archean Tanzania Craton, where my research has focused on gold mineralisation, crustal growth, tectonic evolution, intrusive systems, structural controls on ore formation, and the development of integrated exploration models for world-class gold deposits.
• The Golden Quadrilateral / Patrulaterul Aurifer in the Apuseni Mountains of Romania, where my research focuses on porphyry Cu-Au and epithermal Au-Ag-Te systems in one of Europe’s richest Neogene precious-metal districts. This work examines the links between magmatism, tectonics, hydrothermal alteration, structural control, mineralisation timing and ore-forming processes in the Metaliferi Mountains, with broader implications for porphyry–epithermal transitions and exploration models in young volcanic arcs.
• Northeast Egypt and the Arabian-Nubian Shield, where my work includes REE, Nb and Ta mineralisation hosted by Precambrian granites and pegmatites, as well as broader questions of crustal evolution, magmatism, deformation and metallogenesis along major tectonic structures such as the Najd Fault System.

My research uses a multidisciplinary approach that integrates field geology, structural geology, geological mapping, geochemistry, mineralogy, mineral chemistry, metamorphic petrology, igneous petrology, geochronology, isotope geochemistry, geophysics, numerical modelling and thermodynamic modelling.

My analytical and technical experience includes U-Pb dating of zircon, titanite and monazite by LA-ICP-MS; Lu-Hf isotope analysis by LA-MC-ICP-MS; in situ trace-element analysis; EPMA; SEM; Raman spectroscopy; SWIR spectroscopy; synchrotron X-ray tomography; XFM trace-element mapping; Sm-Nd, Re-Os, C, O and S isotope systems; magnetic, radiometric, gravity, seismic, IP and EM datasets; numerical modelling with Abaqus; thermodynamic modelling with Thermocalc, Theriak-Domino and Perple_X; geochemical modelling with ioGAS; and 3D geological modelling and visualisation using Leapfrog, Datamine and Drishti.

I have led or contributed to a large portfolio of externally funded research projects across economic geology, critical minerals, tectonics, metallogenesis, geochemistry, geochronology, geophysics, ore-deposit characterisation and exploration technology. These projects span regional-scale mineral-system studies, mine-scale geological and structural models, mineral-chemistry vectoring tools, hydrogeochemical and isotope exploration methods, geophysical interpretation, automated mineral chemistry, EarthBank geochemistry, and critical-minerals research.

Training and workforce development are central to my role. I supervise and co-supervise Honours, Masters and PhD students on industry- and government-linked projects, with many students working directly on applied mineral-exploration and ore-deposit problems. I have supervised or co-supervised more than 40 research students across economic geology, structural geology, geochemistry, geochronology, metamorphic petrology, critical minerals and mineral exploration.

I also contribute to professional development and industry training in field geology, structural geology, exploration geology, geochronology, petrography, mineral systems and critical minerals. Through EGRU and the Critical Minerals Trailblazer, I aim to strengthen collaboration between JCU, the minerals industry and government; support responsible resource development; and train the next generation of highly skilled geoscientists for Queensland, Australia and the global minerals industry.
