Ghislaine Crozaz (born 1939[1]) is a cosmochemist known for her research on the early history of the solar system through tracking trace elements in meteorites.
[2] She moved to Washington University in St. Louis as a postdoctoral investigator in the lab of Robert M. Walker (physicist).
As of 2021, she is professor emerita in Earth and Planetary Sciences at Washington University in St. Louis[3] and lives in Brussels.
[1] While a Ph.D. student, Crozaz pioneered the use of lead-210 to establish ages in ice cores in Antarctica[5][6] and Greenland.
[10][11] Crozaz went on to work with Ernest Zinner to develop an ion microprobe method to measure rare earth elements in the individual crystals found in extraterrestrial and terrestrial rocks.
