The Melbourne University Isotope Geochemistry group was established in 1994 by Janet Hergt and Jon Woodhead. We have grown a great deal over the years and now constitute a major research team within the School of Earth Sciences. We have 8 academic staff and typically 5-10 PhD and several Master/Honours students at any given time. We publish around 25 peer-reviewed papers per year, and provide analytical  services to a wide array of academic and industry partners both within Australia and overseas.
