Fe Partitioning in Lower Mantle

Feb 2023 - Present

Fe partitioning among lower mantle phases has non-monotonic behavior owing to the high-spin to a low-spin crossover of iron in ferropericlase (Fp) at pressure-temperature conditions of this region.

Lower Mantle Mineral Studies

Jan 2022 - Present

First part: study the post-perovskite transition in Fe- and Al-bearing bridgmanite. Final target: organize ab initio results and engage in packages and database.
