Professor
Professor Stephen Eggins is an Honorary Professor in the Research School of Earth Sciences (RSES) at the Australian National University (ANU). He previously served as Director of RSES from 2015–2020 and held academic positions including Professor (2015–present), Senior Fellow (2007–2014), and Fellow (2001–2007). His research focuses on biomineralization processes in marine calcifiers, geochemical proxies for ocean and climate history, and the impact of ocean acidification. Eggins has extensive expertise in laser ablation ICP-MS techniques and pioneered advancements in microanalysis for environmental and archaeological applications. Education: PhD (Geochemistry, University of Tasmania, 1991), BAppSc (Hons, University of NSW, 1985). Early career included ARC postdoctoral fellowships (1991–1999) and research roles at ANU's Department of Geology and RSES. Research Interests: Novel isotope and trace element approaches to study marine calcifiers (e.g., corals, foraminifera), development of geochemical proxies for paleoenvironmental reconstructions, and investigating biomineralization mechanisms. Current projects include lab cultures of marine organisms under controlled conditions to assess shell chemistry responses to environmental changes and exploring mitigation strategies for ocean acidification. Key Projects: 'Developing ultra-green hydrogen technologies,' 'Biominerals as environmental archives,' and studies on coral reef pH dynamics and crustose coralline algae dissolution. His work integrates advanced techniques like LA-ICPMS, microCT, and isotopic markers. Teaching: Courses include EMSC1006 (Earth System Science), EMSC3023 (Marine Biogeochemistry), and EMSC3019 (Coral Reef Field Studies). Located at Jaeger Building 8, Level 3, ANU.
