معرفی
Dan Asael is an Associate Research Scientist at Yale University's Department of Earth and Planetary Sciences. His work focuses on metal stable isotope fractionation in geological systems, with expertise in copper, lithium, and molybdenum isotope geochemistry. He has held postdoctoral positions at the University of Liège, Université de Bretagne Occidentale, and IFREMER in France, where he managed MC-ICP-MS laboratory operations.
- Education: PhD in Earth and Planetary Sciences (Yale University)
His research explores paleo-redox conditions through isotope studies of black shales, hydrothermal systems, and sedimentary deposits. Key projects include investigating copper isotope fractionation mechanisms in the Kupferschiefer and Timna Valley deposits, documenting environmental changes during the Great Oxidation Event, and developing soil-based methods for monitoring enhanced rock weathering. Recent publications highlight his work on silicon isotopes in biomineralizers, lithium isotopes in tropical weathering systems, and multi-isotope approaches to Earth's redox evolution.
Current research trends include:
- Development of isotopic proxies for ancient atmospheric oxygen levels
- Hydrothermal fluid metal cycling dynamics
- Climate change mitigation through weathering-based carbon sequestration
- Experimental and theoretical modeling of isotope fractionation
As MC-ICP-MS lab manager, he advanced isotopic measurement methodologies and mentored students in clean lab techniques. His cross-institutional collaborations span geochemical studies of Precambrian iron formations, Neoproterozoic Congo sediments, and modern hydrothermal systems in the Okinawa Trough and Ryukyu Arc.
