Chris has been the Group Geophysicist for First Quantum Minerals, a world-wide base metals miner, since late 2008. Previously, he held a similar role for four years with gold company Resolute Mining Ltd, following completion of a PhD at UWA and CSIRO in crustal geodynamics and interactive geophysical inversion. Before moving to Australia in 1999 as a visiting researcher at CSIRO, Chris worked in gold exploration in West Africa for Placer Dome.


Ph.D. Geophysics, 2004. University of Western Australia, Perth, Australia
M.Sc. Geophysics, 1996. University of British Columbia, Vancouver, Canada

B.Sc. (honours) Geophysics, 1993. McGill University, Montreal, Canada

Current Professional Memberships

Australian Society of Exploration Geophysicists (Active), Australian Institute of Geoscientists (Member), South African Geophysical Association (Member)

Research Interests

Chris is generally interested in integrating geology and geophysics for the purposes of mineral exploration, and bringing research results into the mining industry for practical application as soon as possible. He fancies himself as a geophysicist who tries to become a bit more of a geologist and geochemist with every passing year. Chris is keen to push geophysics into resource modelling and the mining operation at one end of the spectrum, and relishes greenfields targeting and area selection at the other end. Chris is a strong supporter of sharing data and providing data for research, and recognises that the best advances come from cross-disciplinary ideas. His enthusiasm for mentoring has translated into continuous involvement in student supervision from BSc to PhD levels, with previous students at universities in Australia, Mali, Tanzania, and Finland.
