The theory of plate tectonics describes how the rigid plates at the surface of the Earth are formed and destroyed, and how they move over a time scale of millions of years. These plates, which may contain continents or oceans or both, make up a rigid outer shell of the Earth called the lithosphere. My research involves improving our understanding of how continental lithosphere forms, how it preserved, and how it has been changed after its formation. I am focussing on studying the lithosphere of the Precambrian shield in central Canada that was formed between about one and three billion years ago.

板块构造理论描述了地球表面的刚性板块是如何形成和破坏的，以及它们是如何在数百万年的时间尺度上运动的。这些板块可能包含大陆或海洋，或两者兼而有之，它们构成了地球坚硬的外壳，称为岩石圈。我的研究涉及提高我们对大陆岩石圈如何形成、如何保存以及形成后如何变化的理解。我专注于研究加拿大中部前寒武纪地盾的岩石圈，它形成于大约10亿到30亿年前。
