Brief biography

Dr. Michelle Gray is a professor of environmental management at the Faculty of Forestry and Environmental Management at the University of New Brunswick. She is also a Science Director with the Canadian Rivers Institute (CRI). She holds a BSc in Biology and Environmental Science and an MSc in Watershed Ecosystems (Trent University), with a PhD in Biology (UNB) and specializes in aquatic environmental monitoring and assessment.

Michelle has been involved with the development and refinement of guidelines for the federal Environmental Effects Monitoring (EEM) program and for aquatic monitoring in Northern Canada. She has designed and conducted aquatic monitoring programs related to diamond and gold mines, pulp mills, agriculture, and shale gas development. Michelle teaches on environmental management tools, impact assessment, and practical online and field skills training such as the Canadian Aquatic Biomonitoring Network (CABIN), electrofishing, and water quality data analysis. Her current research interests continue to look at novel and integrated tools to assess aquatic environmental health, and the utility of small-bodied fish species in monitoring by investigating their basic life history characteristics.
