Overview

The geochemistry of ground and surface waters, application of stableand radiogenic isotopes to water systems, the relationship between natural and human sources of metals in the environment and rare earth element distributions in terrestrial waters and sediments are the main areas of research interest.

Research Interests

I have several areas of active research including:

  • Geochemistry (major and trace element) of ground and surface waters from diverse geological settings including around massive sulfide deposits in eastern Canada, Cu deposits in Chile, agricultural areas in Manitoba and Nova Scotia, and around a meteorite impact structure in Manitoba.
  • Application of stable and radiogenic isotopes to ground and surface water systems.
  • The relationship between natural (geogenic) and human (anthropogenic) sources of metals in the environment.
  • Igneous petrogenesis, including modern mid-ocean ridge systems (Juan de Fuca Ridge) and ancient systems (early Proterozoic island arc and backarc systems in Saskatchewan).
  • Hydrothermal systems.
  • Processes controlling REE (rare earth element) distributions in terrestrial waters and sediments.
