Isotope and trace element geochemistry, geochronology (mantle evolution, climate change, ore deposit formation)
Professor Hergt completed her PhD at the Australian National University in 1987 and undertook post-doctoral research in the United Kingdom. She returned to Australia and was awarded an ARC QEII Research Fellowship, joining the University of Melbourne in 1994 and establishing state-of-the-art research laboratories. The main focus of her research has been in the application of radiogenic isotope analysis, in combination with other geochemical data, to explore the record of Earth processes preserved in geological materials. Much of this has involved the investigation of igneous rocks and minerals (e.g., continental flood basalts, arc and back-arc magmas, granites, kimberlites, greenstones), but similar techniques have been successfully applied to studies of the regolith, ore deposits and interdisciplinary projects in archaeometry and the biological sciences (www.isotopegeoscience.org). Professor Hergt has served or currently serves on a number of Editorial Boards and is a member of the National Committee for Earth Sciences. She was the Head of Earth Sciences from 2005 to 2013 and served a 7 month term as Dean of the Faculty of Science. She is currently Deputy Dean of Science.
