Twin goals constitute my planetary vision. First, to model sediment evolution remotely, in situ, and terrestrially. Second, to discover the exobiology potential of planetary regolith. I develop and deploy GIS-statistical methods as the path to this vision, with NASA-funded interdisciplinary collaborations within and beyond LSU. Two of my four 2013 projects with Martian “soil” exemplify these goals: revealing hydrous Fe3+ sulfates as the primary bulk sediment hydration phase in the Southern Hemisphere, and automating sedimentological analyses of images from rovers.
