9629018 Wysession The P.I.'s research involves using seismology to map the interior of the Earth, and interpreting these maps to understand the big picture of what our planet is made of and how it works. Just as medical doctors use a sonogram or CAT-scan to image a patient, he uses the reflecting and refracting waves from large earthquakes to image the Earth. This most significant contributions have come through the mapping of the highly variable boundary between Earth's core and mantle, half-way to the center of our planet. This information has helped change the ways geologists perceive the dynamic processes at work inside the Earth. Over the next five years he will continue to develop his research program in the mapping of Earth structure in several directions. He will concentrate on the core-mantle boundary region, but will examine other regions of the Earth, including the Earth's core, the olivine phase transitions at depths of 410 and 660 km, and the upper mantle structure beneath spreading plate boundaries.

9629018 Wysession P.I. 的研究涉及使用地震学来绘制地球内部地图，并解释这些地图以了解我们的星球由什么组成及其如何运作的总体情况。 正如医生使用超声波或 CAT 扫描对患者进行成像一样，他也利用大地震的反射波和折射波对地球进行成像。 这一最重要的贡献来自于绘制地核和地幔之间高度可变的边界（位于地球中心的一半）。 这些信息有助于改变地质学家感知地球内部动态过程的方式。 在接下来的五年中，他将继续在多个方向上发展他的地球结构绘图研究计划。 他将集中研究地核-地幔边界区域，但也会研究地球的其他区域，包括地核、410 公里和 660 公里深处的橄榄石相变，以及扩张板块边界下方的上地幔结构。
