Foreland basins, that are eventually deformed and incorporated within fold-thrust belts in collisional orogens, are hosts to outstanding reserves in hydrocarbon resources around the world. Hydrocarbon bearing fluids trapped within foreland basin sediments will migrate from source rocks to reservoirs at any given time and anywhere within the deforming orogen. Fundamental studies in structural geology are essential to understanding syntectonic fluid flow in foreland basins and fold and thrust belts. Understanding the origin, development and geometry of fracture and fault patterns in various geological structures and how these patterns affect flow is extremely useful in providing appropriate foundations for fluid flow studies and solving fracture flow problems. The long term objective of my research program is to improve our understanding of fluid flow in fold and thrust belts by investigating the genetic relationship between development of structural features and fractures and their spatio-temporal interaction with fluid migration.

前陆盆地最终在碰撞造山带的褶皱冲断带内变形合并，在世界范围内蕴藏着丰富的油气资源。前陆盆地沉积物中的含烃流体在变形造山带内的任何时间、任何地点都会从烃源岩向储层运移。构造地质学的基础研究是认识前陆盆地和褶皱冲断带同构造流体流动的基础。了解各种地质构造中裂缝和断层模式的起源、发展和几何形态，以及这些模式如何影响流动，对于流体流动研究和解决裂缝流动问题提供适当的基础是非常有用的。我的长期研究目标是通过研究构造特征与裂缝发育的成因关系及其与流体运移的时空相互作用，提高我们对褶皱和冲断带流体流动的认识。
