Research Scientist -Environmental Risk Management

I review environmental impact assessments of mining and milling projects across Canada and provide advice to the Office of the Chief Science Advisor and decision makers at the Impact Assessment Agency of Canada.

In addition, I study the environmental movement of radionuclides and metals in aquatic ecosystems and their impacts to aquatic organisms downstream of mining and milling facilities. I also study selenium cycle in passive treatment systems

Current research and/or projects

1- Lithium geochemistry in tailings and waste rock; ecotoxicology

2- Radium-226 toxicity to freswater species of North America

3- Linking historical metal exposure to sediment DNA as a proxy of impacts to fish and their habitat
