Ryan Zeigler is NASA's Apollo Sample Curator and the Manager of the Astromaterials Acquisition and Curation Office of the Astromaterials Research and Exploration Science (ARES) Division at the Johnson Space Center. The principal focus of Zeigler's research is the geochemistry and petrography of lunar samples to better understand how the Moon formed, how it differentiated and how impacts have subsequently altered its surface. In recent years he has performed concentrated research on lunar meteorites and small glass fragments found in the Apollo soils to a better understand how the Moon evolved. In his work as supervisor, he oversees a team of scientists who curate and study NASA's collection of extraterrestrial materials from the Moon, Mars, asteroids, comets, the Sun and even other stars.
