About
Julie K. Bartley is a geobiologist whose research bridges the fields of paleontology, sedimentology, and planetary science, with a particular focus on understanding early life on Earth and informing the search for life on Mars. Her major contributions center on optimizing robotic sample selection protocols for extraterrestrial exploration. Through her leadership in the GeoHeuristic Operational Strategies Test (GHOST) field tests, Bartley has pioneered methods to evaluate and improve the efficiency of rover science operations. Her most cited work (8 citations) examines whether a linear or walkabout protocol is more effective for choosing biologically relevant samples in small regions of interest, using field tests at Mars analog sites to inform mission planning for NASA’s Mars 2020 rover. A second influential paper (3 citations) further tests Mars Science Laboratory data-acquisition and decision-making methods, providing critical insights for robotic sample selection. Bartley’s work directly impacts how future missions prioritize sampling locations to maximize the discovery of biosignatures, making her a key figure in astrobiology and planetary exploration. Her research not only advances our understanding of ancient microbial life on Earth but also shapes the operational strategies that will guide humanity’s search for life beyond our planet.
