Biography
Jemma Davidson is the Branch Chief of the Astromaterials Acquisition and Curation Office (XI2) in the Astromaterials Research and Exploration Science (ARES) Division at the Johnson Space Center. Jemma is also the Astromaterials Curator, the Head Curator for NASA's Astromaterials Collections.
As an isotope cosmochemist and petrologist, Jemma has almost two decades of experience studying a wide range of extraterrestrial materials via numerous analytical techniques. Her research focuses on the petrology and isotope chemistry of a wide variety of astromaterials, including interplanetary dust particles, meteorites from Mars, the Moon, and the asteroid belt, dust from extinct stars, and samples of lava flows collected on Earth. She has also studied samples from several sample return endeavors, including Apollo, Hayabusa, and Hayabusa2.
Jemma’s broad analytical expertise includes secondary ionization mass spectrometry (NanoSIMS, ims-1280, ims-6f), microRaman spectroscopy, electron microprobe analysis (Cameca SX-50 and SX-100, JEOL JXA-8500F HyperProbe and 8900 SuperProbe), optical microscopy, and synchrotron-based X-ray Absorption Near-Edge Structure spectroscopy (XANES). She also has extensive sample preparation experience, from the micro- to macro-scales, including micro-manipulation of small particles (micrometeorites, IDPs, and insoluble organic matter), ultramicrotomy of organic matter, anhydrous polishing methods, epoxy- and indium-mounting, and focused ion beam lift-out.
