He is currently exploring the surface of Mars with the NASA Curiosity team. Dr. Ewing studies how wind shapes planetary surfaces and how the resulting geomorphic record is archived in ancient rocks. His research uses field work, remote sensing, and numerical modeling to unravel the paleoclimate and paleoenvironmental records locked within these wind-blown sediments and rocks across these worlds. Dr. Ewing’s presentation is titled, “Mars’ Past and Present Dynamic Environments.”
