معرفی
Dr. Mattias Ek is a Lecturer at the Department of Earth and Planetary Sciences, ETH Zurich. His research focuses on cosmochemistry, isotopic geochemistry, and the origins of meteorites and planetary materials. He investigates nucleosynthetic processes in stars, isotopic heterogeneity in chondrites, and the formation history of asteroids such as Bennu. Ek teaches courses like Planetary Sciences: a Chemical Perspective and Introduction to Planetary Science at ETH Zurich.
His work combines experimental geochemistry with analytical techniques to study elemental and isotopic compositions in meteorites, shedding light on solar system evolution and stellar nucleosynthesis. Key themes include stardust origins, planetary differentiation, and the interplay between cosmic ray exposure and isotopic signatures in iron meteorites.
Recent publications emphasize Bennu's genetic links to CI chondrites, constraints on stellar sources of isotopes like 150Nd, and advancements in ion-exchange protocols for precise isotope analysis. His contributions bridge astrophysics and geochemistry, addressing fundamental questions about the solar nebula and asteroid formation dynamics.
