Research Profile

${vImageAlt}
Dr. Hecker’s research focuses on ecological and chemical risk assessment, water quality assessment and investigation of the effects of chemicals on aquatic wildlife (fish and amphibians). The ultimate goal of his research is to generate novel information and provide improved strategies and expertise to academic, public, and private sector organizations in support of the protection of aquatic ecosystems and sustainable management of Canada’s natural resources.  These activities contribute to national (Canadian Water Network; Department of Fisheries and Oceans; Environment and Climate Change Canada; US-Environmental Protection Agency) and international (OECD) programs by addressing issues of societal relevance including water security, chemical safety, and protection of the environment.
