As an isotope geo/cosmochemist, Nicole Nie’s research focuses on the application of non-traditional stable isotopes to solving important questions in geochemistry, cosmochemistry and planetary sciences. She uses isotopes in meteorites and ancient terrestrial samples to trace processes that happened in the early solar system, such as planetary accretion and differentiation, volatile element depletion, Moon formation, and planetary surface weathering. The analyses of isotopic compositions of rocks are mainly carried out by combining wet chemistry element purification in a clean lab environment and high-precision measurements using Multi-Collector Inductively Coupled Mass Spectrometer (MC-ICPMS).
Nie received a B.S. in geology from China University of Geosciences in 2010, an M.S. in Geochemistry from Chinese Academy of Sciences in 2013, and a Ph.D. in Geo/Cosmochemistry from the University of Chicago in 2019. After graduating she was a Carnegie Postdoc Fellow at Carnegie Institution for Science, and a postdoc researcher at Caltech before joining EAPS faculty.
