As a cold regions hydrologist, I am interested in how climate change impacts on the permafrost environment (i.e. deep ground thaw, slope disturbances, and permafrost degradation) will alter the surface and subsurface flowpaths of water, and the quality of water in streams and rivers. How, where and when water flows are key controls to the mobilization of solutes, nutrients and sediments in an Arctic watershed. My work involves a variety of field and analytical methods including frozen soil core drilling, discharge monitoring, sampling of surface water, precipitation and ground water, and stable isotope ratio and ion concentration analyses. My main study site is Cape Bounty, Melville Island, NU, however my collaborative research with ADAPT (Arctic Development and Adaptation to Permafrost in Transition) has given me the opportunity to partner with several laboratories in Canada and work with permafrost samples from across the Canadian Arctic.
My research looks at the spatial and temporal dynamics of soil nutrients in High Arctic wetlands. I am interested in seeing how the nutrient cycles, specifically nitrogen, are influencing biophysical processes like carbon fluxes and trace gas emissions and whether there are spatial and temporal variations in nutrient availability throughout the growing season. Coming from a remote sensing background, I am also looking at how the physical aspects of these High Arctic wetlands are seen through satellite imagery.
My research focuses on the fluvial impact of landscape disturbance in the Canadian High Arctic. In particular, I am interested in the downstream geomorphic response and recovery processes following recent permafrost disturbances (active layer detachments). To address this goal, my research evaluates sediment and organic carbon mobilization, storage, and transport processes, specifically in regard to hillslope-to-channel connectivity.

My research will try to numerically model the seasonal change in Dissolved Organic Carbon (DOC) flux in surface runoff in high arctic watersheds. My goal is to develop a numerical approach in modelling this change to help understand impacts of climate change on permafrost environments. I will run the numerical model of the studied water on SWAT (Soil and Water Assessment Tool), which has proven to present hydrological and biogeochemical systems per HRU (Hydrological Response Units). The numerical model will be applied for the West River at Cape Bounty Arctic Watershed Observatory (CBAWO), with the aim to develop a tool/method that is appropriate for modelling the hydrology and the biogeochemistry of other high-arctic watersheds.

My thesis focuses on the West catchment of the Cape Bounty Arctic Watershed Observatory where widespread active layer detachments occurred in 2007-2008. Through the molecular-level characterization of soil and sedimentary organic matter his work aims to reveal compositional shifts attributed to the disturbances
