Dr. Isaac Onyett

Biography

Isaac Onyett is an isotope geochemist specializing in the origins of terrestrial planets and celestial bodies. He employs high-precision isotope measurements on both terrestrial and extraterrestrial samples to understand their formation. Currently, he holds the position of Marie Curie Research Fellow, where his research focuses on the early stages of the solar system, particularly the formation of terrestrial planets and asteroids, which are considered to be the building blocks of our planetary system. His work involves examining the mass-independent isotope composition of solar system materials with the aim of uncovering the origins of celestial bodies and understanding the transport and processing of materials during the initial million years of the protoplanetary disk's evolution. In recent years, he has developed methodologies to utilize mass-independent tracers, with a keen interest in silicon isotopes. His current research centers on studying the mass-independent isotopic composition of silicon and chromium in chondrules, which are early-formed silicate melt spherules, and aims at tracing the origins of the disk. This research is complemented by short-lived radiometric dating techniques, specifically Al-Mg dating, to provide additional temporal insights into early solar system processes.
