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的内部，并解释这些地图，以了解我们星球所构成的东西及其运作方式的大图。 正如医生使用超声图或猫扫描对患者的成像一样，他也使用大地震中的反射和折射波来形象地球。 这项最重要的贡献是通过地球核心和地幔之间高度可变边界的映射，即我们星球中心的一半。 这些信息有助于改变地质学家对地球内部动态过程的看法。 在接下来的五年中，他将继续在几个方向上的地球结构映射中制定他的研究计划。 他将集中在核心壳边界区域上，但将检查地球的其他区域，包括地球核心，410和660 km的橄榄石相变的橄榄石相变，以及在扩散板边界以下的上层结构。
