Dr. James Tuttle Keane

I am currently the Joint Center for Planetary Astronomy (JCPA) postdoctoral fellow in the Division of Geological and Planetary Sciences at the California Institute of Technology. 


I am interested in the formation and evolution of solar system planets, satellites, and small bodies. My primary focus is on how tides, rotation, and geologic processes interact and shape terrestrial and icy worlds. I employ a combination of analytical and numerical methods, and use a variety of spacecraft-derived datasets, including planetary gravity, topography, and imagery.


Beyond research, I am a scientific illustrator, specializing in pen and pencil illustrations of planetary science and geoscience research. My illustrations have been published in Nature Geoscience and Nature Astronomy, and I am the resident illustrator on the New Horizons science team. You can find my live-sketches of scientific conferences (e.g., LPSC, AGU, DPS) on Twitter.
