    Dr. McAdam is a Research Space Scientist in the Planetary Environments Laboratory at NASA’s Goddard Space Flight Center. She is a geochemist with a research emphasis on the mineralogy and chemistry of planetary materials and their analogs.  She specializes in analyses of terrestrial Mars analogs to gain insight into potential martian alteration processes, and the implications of those processes for the habitability of environments on Mars.  She has experience collecting samples from several terrestrial Mars analog environments, and interrogating these samples with a variety of analytical techniques, such as transmission electron microscopy (TEM), secondary electron microscopy (SEM), x-ray diffraction (XRD), and evolved gas analysis (EGA).  A major research endeavor has been performing EGA studies of Mars analog minerals and materials in support of similar measurements that are being taken on Mars by the Sample Analysis at Mars (SAM) instrument on the Mars Science Laboratory (MSL) mission.
