Overview
Background
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.

Research impacts
Key impacts of Prof. Webb's research include: demonstration of the role of microbes in reef building through geological time; establishment of the value of modern and ancient microbialites as proxies for environmental geochemical signatures; application of environmental geochemistry to new coral reef samples made available through UQ's new research vessel the RV D Hill and to late Pleistocene vertebrate remains in Queensland that demonstrate recent, pre-anthropogenic changes in Queensland's climate. The integration of well dated fossil remains from both terrestrial and marine environments with high quality geochemical analysis allows specific hypotheses to be tested that provide information directly useful for testing climate models and the effects of pre-instrumental climate change and anthropogenic forcing on Australian faunas and ecosystems.
