Welcome to the Isotope Cosmochemistry Laboratory directed by Prof. Kun Wang (王昆) in the Department of Earth & Planetary Sciences at Washington University in St. Louis.

Our lab works on a variety of samples including meteorites, lunar rocks and rocks on the Earth. Our research interests focus on:

• Origin of the Earth and of the Solar System
• Planetary differentiation: core-mantle segregation and crust formation
• Transition metal isotope geochemistry
• Analytical development and application of high precision isotopic measurements using Multi Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS)
