Research Interests

My research interests focus on modern riverine landscapes but also on using paleoflood sedimentary and hydrologic techniques at explaining current landscape evolution. My current research on Medway Creek explores glacial till erosion, channel alluviation and bedform morphology of semi-alluvial channels that are typical to the Great Lakes region but also to other formerly glaciated terrains.    

  • Quaternary geology and geomorphology
  • Sediment transport in gravel-bed streams
  • Hydro-ecology
  • Using water resources in conjunction with natural requirements
  • Stream restoration
  • Wetland hydrology and sedimentology
  • Catastrophic flooding and paleofloods as tools for predicting future flood hazards and climate change
  • Anthropogenic effect on the riverine environment

Why Western

I chose to continue my graduate education in Geography at UWO because of the unique semi-alluvial channels surrounding the campus and allow continuous observations at a walking distance. In addition, my supervisor has a state of the art wide flume that allow to conduct small scale experiments and modeling that cannot be done in the field.
