My research focuses on Arctic and Sub-Arctic Systems and combines the use of GIS and remote sensing techniques with field observations and laboratory analyses to better understand the causes and consequences of landscape change, processes, and feedbacks in northern high latitude environments across a multitude of spatial and temporal scales. I specialize in observing, understanding, and interpreting present as well as past permafrost region landscape dynamics and the various landscape-level impacts to hydrological, ecological, and physical systems.
