Elizabeth M. Spiers, PhD

Planetary scientist interested in the habitability & exploration of ocean worlds within our Solar System.

I am a research associate at the University of Texas at Austin’s Institute for Geophysics.

My research interests are in quantifying and constraining the dynamic habitability of ocean worlds in our Solar System, such as Jupiter’s moon, Europa, and Saturn’s moon, Enceladus. I use system models to examine global-scale energy and chemical changes within these oceans over time. This research will improve our understanding of the interior composition of ocean worlds, informing and providing constraints for future missions, such as NASA’s Europa Clipper which will launch in October 2024. As a graduate student, I was an affiliate of Europa Clipper’s REASON instrument, an ice-penetrating radar, and I have been participated in a number of planetary mission and instrument development projects, with an emphasis on life detection strategies for ocean worlds.
