Biography
Devin Schrader is a Space Scientist in the Research Branch (XI3) of the Astromaterials Research and Exploration Science (ARES) Division at the Johnson Space Center.
As a cosmochemist and petrologist, Devin’s research focuses on lunar meteorites, samples returned from the Moon, samples to be returned from Mars’ moon Phobos, primitive meteorites that remain relatively unaltered since their formation in the early Solar System, and meteorites that were thermally and aqueously altered on their parent asteroids. He uses petrographic, compositional, thermodynamic, and isotopic data to investigate the conditions under which these materials formed before accretion, as well as the secondary thermal and aqueous processes that modified small and large Solar System bodies.
Devin’s analytical experience includes electron probe microanalysis (Cameca SX-50 and SX-100, and JEOL JXA-8500F/8530F Hyperprobe and 8900 Superprobe), scanning electron microscopy, optical microscopy, in situ secondary ion mass spectrometry (Cameca ims-1280), focused ion beam techniques, gas mixing lines, quadrupole mass spectrometry, high temperature horizontal tube furnace, and bulk sample O-isotope mass spectrometry via laser fluorination.
