Researcher biography
Prof. Gregory E. Webb is a palaeontologist and carbonate sedimentologist who has occupied the Dorothy Hill Chair of Palaeontology and Stratigraphy at the University of Queensland since 2011. He is the head of the Integrated Palaeoenvironmental Research Group in the School of Earth Sciences. He obtained his BSc in Geology with highest honours at the University of Oklahoma (OU-1983) followed by an MSc in Geology (OU-1984) and a PhD in Palaeontology at The University of Queensland in 1989. His research interests are clustered within the fields of carbonate petrology, reef palaeobiology, geomicrobiology, carbonate geochemistry and carbonate stratigraphy. These fields have major implications for understanding Earth history, palaeoclimatology, and mineral and energy exploration. In general, Prof. Webb's research focuses on understanding how organisms make rocks – how the biosphere interacts with the lithosphere through time - and how those rocks are preserved and how they record evidence of past environmental conditions in their geochemistry.
