Dr. James Tuttle Keane hails from Cedar Rapids, Iowa. He received a bachelor’s degrees in Astronomy and Geology from the University of Maryland, College Park, and a doctorate in planetary science from the University of Arizona, under the mentorship of Dr. Isamu Matsuyama. After a postdoctoral position at the California Institute of Technology, he started at JPL in 2020.
Dr. Keane is a planetary scientist, studying the interactions between orbital dynamics, rotational dynamics, and geologic processes on rocky and icy worlds across the solar system. He uses a combination of theoretical methods, coupled with the analysis of spacecraft-derived datasets to investigate the dynamics, structure, origin, and evolution of solar system bodies. He has extensive experience with NASA missions, including GRAIL, New Horizons, and the proposed Io Volcano Observer.
In addition to science, Dr. Keane is an accomplished science illustrator and communicator, specializing in pen and pencil illustrations of planetary science concepts, new results, and exciting missions.
