Dr. Stephen Eggins

Biography

I began my research career in igneous petrology and geochemistry with David H Green at the University of Tasmania, moving to the Australian National University to hold an ARC postdoctoral fellowship in Malcolm McCulloch's group. I developed novel ICP-MS methods that enable precise and accurate analysis of trace elements in basalts and mantle samples. These techniques provided the foundation for developing ANU's world-leading HelEx laser ablation ICP-MS technology in partnership with Michael Shelley and Les Kinsley. I pioneered the use of deep UV lasers and laser sampling cell designs that have become widely adopted by manufacturers and research laboratories worldwide. My research has subsequently focused on applying LA-ICP-MS in novel ways to address problems in environmental geochemistry and the dating and reconstruction of marine biogeochemistry, particularly the biomineralization processes of marine calcifiers, with a specific focus on the incorporation of geochemical isotopic proxies in the skeletons and shells of corals, molluscs, and foraminifera to understand past ocean-climate reconstructions.
