Alex Halliday is a Visiting Professor in the Department of Earth Sciences at the University of Oxford. His research focuses on isotope geochemistry and mass spectrometry to study planetary origins and Earth's natural behavior. He specializes in analyzing isotopic variations caused by radioactive decay, fractionation, and cosmic processes to determine ages of geological events and environmental conditions.
- Key techniques: MC-ICPMS (multi-collector inductively coupled plasma mass spectrometry)
- Research collaborations with Gideon Henderson, Don Porcelli, and Ros Rickaby
- Led the establishment of Oxford's advanced geochemistry facilities, including five MC-ICPMS instruments—the largest such suite globally
His work addresses fundamental questions like the Moon's age, Earth's cooling rates, and ocean temperature histories through forensic fingerprinting of geological materials.
