معرفی
Erik Sperling is an Associate Professor of Earth and Planetary Sciences at Stanford University, affiliated with the Stanford Doerr School of Sustainability. He is also a Senior Fellow at the Woods Institute for the Environment and holds a courtesy appointment as Associate Professor in the Department of Oceans. His research focuses on Earth’s environmental and biological evolution, particularly the interplay between atmospheric oxygen levels, marine redox conditions, and the emergence of complex life during the Neoproterozoic and Paleozoic eras.
Research interests include paleoceanography, geochemical analysis of sedimentary records, early animal evolution, and the biogeochemical drivers of mass extinctions. He integrates fieldwork, laboratory geochemistry, and computational modeling to explore topics such as Ediacaran-Cambrian transitions, the role of oxygenation in metazoan diversification, and modern organismal responses to environmental stressors.
His work spans geological time scales, from studying Precambrian shales and stromatolites to analyzing the physiological limits of marine organisms under deoxygenation scenarios. Recent studies emphasize the long-term oxygenation history of oceans, the ecological consequences of hypoxia-temperature interactions, and the application of novel geochemical proxies to reconstruct ancient environments.
Laboratory activities include the Sperling Lab, which develops innovative methods for trace element analysis and integrates multi-proxy datasets to address questions in Earth’s history. Collaborations with institutions worldwide focus on global sedimentary geochemical databases and field projects in regions like the Yukon, Brazil, and Australia.
