  • Noble gas geochronology and geochemistry (Ar-Ar dating, Quaternary volcanism, cosmogenic Ne-21 and He-3 dating)



  • Erin is a noble gas geochronologist, primarily focused on application of the 40Ar/39Ar dating technique to Upper Pleistocene-Holocene samples. Since February 2013 she has been employed as a postdoctoral Research Fellow at the University of Melbourne and, along with Prof. David Phillips, has been undertaking collaborative work with partner TANG3O (Thermochronology and Noble Gas Geochronology and Geochemistry Organisation) noble gas laboratories at Curtin University and the ANU as part of an ARC Discovery Project. Erin has been using a new generation ARGUSVI mass spectrometer to investigate key irradiation standards used for 40Ar/39Ar geochronology, and has been refining procedures for dating young (< 100 kyr) basalts using this system. She also has an interest in other aspects of noble gas geochemistry, such as the study of cosmogenic isotopes of neon and helium in exposure history studies, in addition to complementary methods for dating young volcanic rocks (e.g. U-series disequilibria), and eruption risk in southeastern Australia. Erin is currently Acting Lab Manager of the Noble Gas Laboratory at Melbourne. Erin completed both her undergraduate and doctoral studies at the University of Melbourne, graduating from her PhD in 2012 (thesis title: Calibration of the cosmogenic 21Ne dating method for application to Quaternary volcanic chronology). During the course of her PhD, Erin divided her time between the University of Melbourne and the Australian National University, and conducted fieldwork in Australia (western Victoria), Sicily, Iceland, and the Mojave Desert. Erin is experienced in various mineral separation techniques and has experience with working in a clean lab environment.
