Petrology: Igneous, Metamorphic and Volcanic Studies.
Helen’s research interests center around the application of non-traditional stable isotope systems to understanding the formation and evolution of planetary interiors. Her work includes topics such as accretion, core formation and the evolution of mantle redox state, isotopic tracing of depleted and enriched mantle components, element cycling and the oxidation state of subduction zones and the secular evolution of the Earth’s mantle. Some of her most recent research involved combining stable iron isotope analyses with high-pressure experiments to simulate conditions within the Earth’s interior and the conditions of the Earth’s earliest mantle. Helen has recently been awarded a Euro European Research Council (ERC) Starting Grant for the “HabitablePlanet” Project, and is also collaborating on a number projects using non-traditional stable isotopes to explore weathering processes and biogeochemical cycling
