Curriculum Vitae: 
Education: 

PhD, 2006, Forest Hydrology, University of Alberta

BSc, 2002, Environmental and Conservation Sciences, University of Alberta

Areas of Interest: 
  • Watershed hydrology and management
  • Natural (wildfire, pests) and human (conventional and salvage harvesting) disturbance effects on water quantity, water quality, and aquatic ecology
  • Hillslope runoff and biogeochemical processes
  • Microclimate change and tree-water relations

Research Interests:

My current research interests are to quantitatively explore the impacts of land cover and land use change on hydrology, water quality, and aquatic ecosystem health at the hillslope, stream reach, and catchment scale. My research program also includes regional and state (provincial) scale analyses of spatial and temporal trends in water quantity and quality as related to land use and climate change. Research results should ultimately improve forested source water management and protection strategies by improving the predictive capability of hydrologic and biogeochemical models. I also have interests in continuing to develop high quality, trans-disciplinary research collaborations focused on providing local, regional, national, and international solutions to a diversity of water challenges, including municipal drinking water supply.
