Erin is an Academic Specialist (40Ar/39Ar Geochronology) and Manager of the Ar-Ar Laboratory in the School of Earth Sciences.She is primarily focused on application of high-precision 40Ar/39Ar geochronology (using high-precision multi-collector mass-spectrometry) to Quaternary volcanic samples to better understand eruption hazards and help answer questions in archeological science. Erin is currently a CI on an ARC Discovery Project working on establishing a high-resolution timeframe for hominin evolution in the Omo-Turkana Basin, East African Rift, Kenya.
She has also been investigating the ages and utility of naturally occurring minerals used as flux monitors for 40Ar/39Ar geochronology, improving the accuracy of the technique. She has also refined procedures for precise dating of very young (< 100 kyr) basalts via 40Ar/39Ar geochronology, using samples from the Newer Volcanic Province of SE Australia as case-studies. She is actively involved with a number of research collaborations investigating questions in structural geology, tectonics and economic geology (e.g. timing of orogenesis, gold mineralisation, and kimberlite emplacement) using Ar-Ar geochronology/thermochronology and complementary geochemical techniques. Erin 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). Erin completed both her undergraduate and doctoral studies at the University of Melbourne (PhD thesis title: Calibration of the cosmogenic 21Ne dating method for application to Quaternary volcanic chronology). During the course of her PhD studies, 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.
