Matt Dodd is an environmental analytical chemist with research interests in metal speciation and bioavailability, contaminants in the urban environment, e-waste management, air quality monitoring and management, soil toxicity testing, persistent organic pollutants, microplastics, contaminated sites assessment and remediation, ecological and human health risk assessment, and integrated pest management. He has conducted research and served as project scientist for environmental projects in Canada, China, and Ghana. He has also supervised or provided scientific advice on the remediation of contaminated sites including mines in the Yukon, Northern BC, and the Canadian Arctic (e.g., DEW Line). He supervises thesis, dissertation, and major research project students in undergrad and graduate programs. He has developed and delivered short courses on environmental assessment and remediation to various agencies, successfully incorporating practical experiences from the numerous projects he has worked on.
Experience
Dodd joined Royal Roads University in 1995 as a research associate with the Centre for Economic Development and Applied Research (CEDAR) and moved to the School of Environment and Sustainability in 2006. Prior to this he was a research associate with the Environmental Sciences Group at Royal Roads Military College and taught briefly at Grenfell College, Memorial University of Newfoundland.
