In the last 10-15 years, there has been a remarkable increase in seismic data coverage over much of the North American continent, due to regional and national initiatives to install networks of seismograph stations to record earthquake signals. The seismic waves from global earthquakes, recorded at these stations, provide a wealth of information on Earth structure, as their speed depends on the nature of the rocks through which they travel. My research to date concentrated on establishing seismic models of the crust and upper mantle across regions of central, eastern and northern North America using a variety of methods to capture this structure.

在过去的10-15年里，由于区域和国家采取主动行动安装地震仪台站网络以记录地震信号，北美大陆大部分地区的地震数据覆盖面显著增加。这些台站记录的全球地震的地震波提供了有关地球结构的丰富信息，因为它们的速度取决于它们所穿过的岩石的性质。迄今为止，我的研究集中在建立横跨北美中部、东部和北方地区的地壳和上地幔的地震模型，使用各种方法来捕捉这种结构。
