Research Interests:

  • Applied Ecohydrology
  • Wetland Hydrology and Biogeochemistry
  • Catchment Hydrology and Biogeochemistry
  • Stream and Wetland Restoration
  • Forest Disturbance and Stream Water Quality
  • Urbanization and Water and Solute Cycling

Teaching This Academic Year:

GGR217: Fundamentals of Hydrology (Winter 2015)

Call For Students:

The Stream and Wetland Ecohydrology Research Group is looking for bright, motivated, hard-working students at both MSc and PhD levels to start research projects on urban and urbanizing stream corridor ecosystems. Projects include in-stream biogeochemical cycling and metabolism, groundwater-surface water exchange, stream-riparian-hillslope hydrological interactions, riparian zone nutrient and carbon cycling, and the influences of severe weather events on all of the above. Applicants for these projects should enjoy working outdoors in all weather and/or be comfortable working in a chemical lab setting. There are possible projects for applicants preferring workstation-based data analysis. Additional funding can be provided.
