Brief biography

Dr. Alexander-Trusiak is an Environment and Climate Change Canada research scientist and Visiting Research Professor co-located in the Biology Department at the University of New Brunswick in Fredericton. Dr. Alexander Trusiak’s primary role is in research, development and analysis, with a focus on the development and application of integrated assessment approaches to separate and diagnose the effects of multiple stressors in aquatic ecosystems.

Her research targets critical areas where current environmental guidelines are inadequate or where thresholds for environmental sustainability are required. Her research to date, investigates the combined effects of interacting natural and anthropogenic gradients on the ecological structure and function of riverine ecosystems at multiple spatial and temporal scales.
