My research is focused on advancing our understanding of the linkages between climate, hydrology and geomorphology in permafrost landscapes. This research is driven by the need to understand how terrestrial landscapes are sensitive to climate variability and respond to permafrost change. This is important to predict landscape stability, water quality and downstream effects in natural systems, and to contribute to land use management and protection in Arctic regions. I have worked across the Canadian Arctic since 1988 and have also carried out research in Alaska and Norway. My approach to research is a combination of field-based studies to document processes and fluxes, along with laboratory work to measure water quality, and modelling to predict hydrological systems. I work extensively with both watershed and lake systems and I have a strong interest in the use of sedimentary records as a means to investigate long term changes. I have worked extensively with clastic varved sediments, which provide high resolution chronology to better integrate with contemporary process and environmental data sets.

My current research work is directed at understanding:\
• the magnitude of sediment fluxes from surfaces that have been disturbed by permafrost change at various scales
• subsurface water movement and pathways in permafrost terrain
• hydrological and geomorphic controls over permafrost disturbance
• precision mapping of landscape processes with UAV imaging
• the chemical evolution of the lakes in the region
• the application of hydrological modelling to watershed, sedimentary and geotechnical processes.
