Brief Bio


Dr. Arevalo Jr. is a Research Space Scientist at NASA GSFC with expertise in in situ methods of chemical analysis, particularly: magnetic sector, time-of-flight and ion trap mass spectrometry; laser ablation and desorption sample processing; and, electron probe microanalysis (EPMA) of terrestrial and extraterrestrial materials. His scientific research is focused on analyzing geological samples from the Earth and other differentiated rocky objects, and establishing comprehensive models of the chemical compositions of planetary interiors.
