معرفی
Prof Graham Shields is a Professor of Geology at University College London's Department of Earth Sciences. His research focuses on Earth's evolution through geochemical and isotopic analysis, particularly in the Precambrian and Cambrian periods. He investigates how the planet's surface environment co-evolved with life, with a focus on ocean/atmosphere composition during critical junctures like the Sturtian Snowball Earth event and Ediacaran-Cambrian transitions.
His work combines field studies in Australia, Spain, and China with analytical techniques such as Rb-Sr dating, multi-isotope analysis, and sedimentary proxy development. Research themes include ocean oxygenation, redox dynamics, and the interplay between glaciation, volcanism, and biological innovations. Applied projects explore geochemical solutions for environmental issues like soil erosion and sustainable resource extraction.
He leads the Precambrian Research Group and contributes to initiatives like the Life and the Planet initiative. Publications span Neoproterozoic climate modeling, Ediacaran ocean chemistry, and the geological time scale subdivision. Courses taught include GEOL0008 (Geochemistry).
