Curriculum Vitae:

Research Interests

Dr. Liu's current research focuses on the investigation of extraterrestrial rocks and soils, returned by human or by nature, in order to understand the processes affecting the surface and interior of different planetary bodies. Her research utilizes microscopic mineralogical and geochemical information of rocks and soils to depict the processes occurred on the planetary bodies.

One direction of her research focuses on volatiles, from those on the surface to the interior. Results aim to answer questions such as: What are the sources of surface volatiles observed on airless terrestrial bodies? What is the budget of volatiles on a planetary body? How do they affect magma properties and thus volcanic eruptions?

Second direction involves study of water on Mars. Her research group is developing impact melts as a hygrometer of subsurface and magmatic water on Mars through analytical and experimental approaches. In addition, she and coworkers have been finding unusual minerals in NWA 7034/7533 that record hydrothermal and metamorphic events.

The third direction of her research studies the formation and evolution of the crust and mantle of terrestrial bodies. Basaltic meteorites from the Moon, Mars, and asteroids, albeit their small sizes, carry important information about the crust and mantle. Some of these samples are so ancient that they formed within the first few million years of the Solar System formation. These samples are particularly intriguing for understanding the formation and evolution of the Solar System.
