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学过程在汇编和融合超大型过程中发生。北美东部和西欧的已故古生代阿勒格尼亚人 - 瓦里斯坎造山带尤其重要，因为它们记录了与超大陆Pangea形成有关的一阶过程，这对我们地球许多自然系统产生了深远的影响。因此，对这些山带发展的洞察力将如何有助于我们对过去和现在的全球构造事件的理解。有很多构造模型，它们试图解释Variscan造山基因的地质。但是，当区域构造模型集成到这些模型中时，存在多种矛盾之处，强调了我们对瓦里斯卡岛局部和造型过程的理解之间的基本脱节。此外，缺乏对Variscan Belt中的地球动力学过程与阿巴拉契亚人的已知事件的关系。为了解决这些问题，我将选择一些可以测试竞争对手假设和区域构造模型的关键领域。
