Research Scientist - Study leader, UV impacts on aquatic ecosystem function

Pacific Biological Station (Nanaimo, BC)

CURRENT S&T / RESEARCH - Contributing to Environment Canada’s mandate to ensure wildlife is conserved and protected

• Understanding the role of human activities in the spread of harmful river micro-organisms (didymo) - Helping to develop control procedures
• Determining impacts of human activity and land use patterns on river biota
• Climate change impacts on dissolved organic carbon loading to aquatic ecosystems in the arctic: Human impacts in the North mediated through ultra violet radiation
• Role of solar ultraviolet radiation in the structure, function and biodiversity of aquatic ecosystems
• Developing bioassays for UV radiation exposure of aquatic ecosystems in response to land use activities
