Research interests

Physical Hydrology is the study of physical processes in the hydrologic cycle.

My research generally combines detailed field observation and experiments with mathematical analysis.

The major topics of my current research are the following:

  • Alpine hydrology in the Rockies
  • Permafrost Hydrology in the Sub-Arctic
  • Hydrology of Seasonaly Frozen Soil
  • Prairie Hydrology
  • Hydrology of Banff Hot Springs


The research is carried out by a dedicated group of students, technicians, and postdoctoral fellows .

Please contact us by e-mail , if you want to join our research team. If you are interested in the graduate study in physical hydrology, please look up the Graduate School Info for the Department of Geoscience.

Our research group is part of CREATE for Water Security program.
