Jie Li studies Earth and planetary materials under high pressures and high temperatures, using multi-anvil apparatus, diamond-anvil cells, micro-analytical instruments, and synchrotron radiation facilities. She is interested in the origin and evolution of terrestrial planets, terrestrial-like moons and asteroids in the solar system. Recent topics include:
- Light element composition of the Earth's core
- Spin state of iron in the Earth's lower mantle
- State of Mercury's core and the origin of its magnetic field
- Core formation during the early history of the Earth
- Formation of the Earth's continental crust
Field(s) of Study
- My research group and our collaborators have taken advantage of modern high-pressure and micro-analytical techniques to study the physics and chemistry of materials under deep Earth conditions. To infer the nature and dynamics of the most inaccessible parts of our planet, we combine results in experimental geochemistry and mineral physics with seismic observations, cosmochemical constraints, and dynamic models.
