Helen Williams

Helen Williams is a Researcher at the Department of Earth Sciences, University of Cambridge. Her work focuses on developing and applying novel isotope tools to study geological and planetary processes, including mantle heterogeneity, magma ocean crystallization, and subduction zone redox cycles. She collaborates with geophysicists, volcanologists, and planetary scientists through multidisciplinary team-based research.

• Key research areas: Mantle and core processes, critical metals, planetary habitability, subglacial environments

Her group utilizes high-precision plasma mass spectrometry and fieldwork to analyze natural samples like igneous rocks, meteorites, and sediments. Specific projects address ore deposit formation, volatile element cycling, and the evolution of Earth's interior chemistry over 4 billion years.
