Biography
Kei Shimizu is a Planetary Geochemist working at NASA’s Johnson Space Center as a part of the Jacobs JETS II contract. He is a Cosmochemist/Geochemist with a broad interest in the chemical evolution of the Solar System and Planets/Moons with a particular focus on volatiles (H, C, F, S, Cl). He studies various astromaterials using microanalytical techniques such as secondary ion mass spectrometry (SIMS) and manages the NanoSIMS 50L lab at NASA's Johnson Space Center.
