| Research Abstract |
In this research program, we have unraveled the detailed structure (water content and speciation, cation order/disorder, defect, etc) for a number of important water-bearing mantle minerals and related compounds using advanced multi-nuclear and multi-dimensional NMR spectroscopy. We have also discovered several new high-pressure phases and have determined their crystal structures. Such information is indispensible for understanding the physical properties of minerals at the earth's interior and for modeling the dynamics and evolution of the earth.
