Libby is a JPL Postdoctoral Fellow on the Mars 2020 Science Team. She is a geologist, clastic sedimentologist, geomorphologist, and geologic mapper. Libby developed her expertise by studying a diverse suite of sedimentary systems, landscapes, and depositional processes on Earth. This work was primarily conducted through field observations of such field sites as modern glaciers in Iceland, Quaternary glacial deposits of the northern United States, and Paleozoic successions in Argentina, Australia, and Antarctica. The purpose of this work is to reconstruct what the surface of our planet looked like in the distant (and not-so-distant) past, and to understand the processes that drive changes in surficial systems.
At JPL, Libby is contributing to the Mars 2020 team by helping describe and interpret sedimentary rocks in the Jezero Delta using data collected by the Perseverance rover and by working on a regional geologic map of the Nili Fossae region of Mars.
