معرفی
Dr. William Defliese is a Senior Lecturer in Geochemistry at the University of Queensland's School of the Environment. He holds a Ph.D. in Geology from the University of Michigan (2014) and has held postdoctoral positions at UCLA and Texas A&M University before joining UQ in 2019. His research focuses on clumped isotope geochemistry, sedimentary processes, and paleoclimate reconstruction.
He leads the Carbonate Research and Geochemistry group, advancing methodologies in clumped isotope analysis and their application to diagenesis, basin analysis, and halogen geochemistry. Key areas include clumped isotope reordering kinetics, carbonate sedimentation/diagenesis, and halogen distribution in marine sediments. He collaborates with ANZIC/IODP on oceanographic studies.
Recent work explores Holocene climate change impacts on cultural evolution in Northwest India, Cretaceous oceanic anoxic events, and Snowball Earth glaciation effects on ocean isotopes. His lab develops halogen analysis techniques (combustion ion chromatography) to address gaps in oceanic sediment budgets.
Defliese has supervised multiple Ph.D. projects on topics like monsoon variability, carbonate clumped isotope heterogeneity, and halogen recycling in sediments. Current funding includes projects on halogen content in oceanic sediments and coral paleoenvironmental proxies.
His >30 publications span clumped isotope calibration, basin thermal history, and diagenetic processes. Lab facilities include carbonate precipitation labs and advanced geochemical instrumentation.
