Helen Williams has discovered that iron isotopes become fractionated during mantle melting and redox processes. This was an unexpected result and she has successfully applied this and other heavy stable isotope systems to understand processes including the origin of the Earth’s core and melting beneath mid-ocean ridges, ocean islands and subduction zones. In addition, Helen has served on the European Association of Geochemistry Council, on several committees for the EAG and the Geochemical Society, she co-chaired the 2019 Barcelona Goldschmidt conference and she is an editor for Geochemical Perspectives Letters.
