My main research interests are orogenic processes occurring during the assembly and amalgamation of supercontinents. The Late Paleozoic Alleghanian-Variscan orogenic belts of eastern North America and Western Europe are of particular importance, because they record the first-order processes related to the formation of the supercontinent Pangea, which had profound influences on many of our earth's natural systems. Therefore, insight into how these mountain belts developed will contribute to our understanding of how global tectonic events in both the past and present relate to our natural environment. There are a plethora of tectonic models, which attempt to explain the geology of the Variscan orogen. However, when regional tectonic models are integrated into these models there exists a multitude of inconsistencies, highlighting a fundamental disconnect between our understanding of local and orogen-scale processes in the Variscan. In addition, there is a lack of understanding of how geodynamic processes in the Variscan belt relate to known events in the Appalachians. To address these questions, I will select some critical areas in which rival hypotheses and regional tectonic models can be tested.

我的主要研究兴趣是造山过程中发生的组装和合并的超大陆。北美东部和西欧的晚古生代Alleghanian-Variscan造山带特别重要，因为它们记录了与超大陆Pangea形成有关的一级过程，这对我们地球的许多自然系统产生了深远的影响。因此，深入了解这些山脉带是如何发展的，将有助于我们了解过去和现在的全球构造事件与我们的自然环境之间的关系。有大量的构造模型试图解释华力西造山带的地质。然而，当区域构造模型集成到这些模型中存在着大量的不一致，突出了我们的理解之间的根本脱节的地方和造山带规模的过程中华力西。此外，人们对华力西带的地球动力学过程与阿巴拉契亚山脉的已知事件之间的关系缺乏了解。为了解决这些问题，我将选择一些关键领域，在这些领域中，可以测试竞争对手的假设和区域构造模型。
