Elisabeth (Libby) Hausrath

Associate Professor of Geoscience
Expertise: Mars geochemistry, Water-rock interactions, Astrobiology, Snow dynamics


Elisabeth (Libby) Hausrath is an aqueous geochemist and astrobiologist who investigates interactions between water and minerals, and the impacts of life on those interactions. She and her team use a combination of field work, laboratory experiments, and modeling to investigate signatures of aqueous alteration and life, the rates at which water-rock interactions occur, and how they differ on Earth and on other planets such as Mars. Their work helps understand chemical weathering, water chemistry, nutrient release, the formation of soils, and potential signatures of life on Earth and Mars.

Hausrath and her team also explore snow dynamics, particularly the interactions between snow algae, microorganisms, and minerals in the nutrient-poor environment present in snow, which may also be an analog to Mars.

Hausrath serves on NASA's Returned Sample Science Board, which offers scientific input into aspects of the upcoming Mars 2020 rover mission.
