Biography

Erin Leonard is currently a post-doctoral researcher at the Jet Propulsion Laboratory, California Institute of Technology. Her research focuses on geomorphologic mapping of icy satellites, structural analysis of the surface features, and how these surface observations can lead to implications for the subsurface or evolution of the body. Erin is the lead author on the new global geologic map of Europa for the United States Geologic Survey (USGS) that has been accepted and is currently in press. She also has a particular interest in the Ice Giant systems, with an emphasis on detecting and characterizing Ocean Worlds, and actively aids in formulating and advocating for missions to these systems. Inspired by the work she has done for Europa Clipper Project Science, Erin is also interested in the interface between science and engineering, especially as it relates to operations, systems engineering, and management.
