Steven is a planetary scientist, astrobiologist, Mars 2020 science team member, and JPL postdoc interested in the habitability of past and present Mars. His research focuses on applying quantitative techniques to understand the distribution, magnitude, and timing of past liquid water on the Martian surface using orbiter data. His background is in assessing the evidence of past oceans on Mars, developing automated landform detection tools, and modeling the habitability potential of Mars' atmosphere over time. Approaches include remote sensing, photochemical modeling, field analog studies, spectroscopy, geological mapping, image analysis, and optimization algorithms.
